It also helps when drilling through composites to start out with the drill in reverse which prevents the bit from ripping the fibers. After drilling through the first layer or two, return the drill to normal drive but don't drill all the way through the other side. As the bit starts cutting though the opposite side of the panel reverse the drill again and cut all the way through the panel. This will leave you with a very clean hole through both sides of your panel.
Found your channel when watching videos on longboards as my daughter and I just started skateboarding. What an awesome board and watching the whole process was great thanks 😊
another good video, i still haven't got round to doing any infusions in the garage yet. I think a new coffee table with these materials would be a great gift for the missus :)
Hi Easy Composites, i love your videos and i love composites..i'd like to build a carbon fiber penny board for a friend, how many layers do you recommend to use? Thank you!
Lately, epoxy sand grip is gaining popularity. Is this resin able to spread thinly, bond the sand, and be clear enough to exhibit the grain of the underlying wood/core?
+HumorVortex Mosco I started doing Carbon Fiber in college, and I think the best way to start is to start with making small flat panels out of Carbon Fiber or fiberglass if you cannot afford carbon. From there it is a matter of working your way up to more complex parts and methods of production. Best of luck!
Haha, thanks, but actually I would say that most of what we do in this video is pretty straightforward - you just need to put quite a few steps together! When you can do a composites project without going through the extra work of making a pattern then making a mould (like we do in our airbox video or the bonnet making video for example) then you actually get your results quite quickly - however, it's all relative!
Hy Easy-Composites. I would like to know the dimensons of the board and what was your thickness of the block for the camber. Does the board flex much, or would a smaller camber be possible due to the stiffness? Greetings, Patrick
Thanks Neil. Yes, understandably we're struggling to get the courses restarted at present. Hopefully conditions will change soon. Look forward to welcoming you to Easy Composites.
Thank you so much for making the effort to produce such an incredibly informative video. The design is pretty nice, it's just too bad that the 'pretty' side faces the asphalt, and the up side looks like asphalt - just like every other skateboard. So the question is, if we really want to make progress in the status quo in term of design and materials, what technologies are available for molded in grip surfaces that don't look like asphalt? Of do we just need better shoes?
You could opt for a closed mould process with an upper and lower closed mould tool with a moulded, grip surface. This wouldn't lend itself to one offs as you would be significantly increasing tooling costs but for a series production, there's no reason why closed, compression moulding couldn't be used to give you whatever surface finish you wanted.
Did the wood core soak up a lot of resin? I work making guitars by resin infusion, and would like to try doing a longboard. The guitars are only 4 ply of CF and fiberglass. How much resin and hardener did the longboard take?
The wood soaked up almost no resin but the gaps between the strips of wood did consume some resin. The longboard used about 1kg of resin, I'm afraid we didn't record the exact amount.
Thanks for the suggestion. The next few videos are already in the *pipe* line (pun intended) but we'll certainly add some surfboard ideas into the pot for future consideration.
Good evening I am following your tutorials very carefully, I would like to ask you, how much bio resin you have applied. And if I may ask you for a tutorial how to make a helical blade. Thanks Maurizio
Love your videos, I work in at a London university and use your products on a regular basis. would you be able to use a similar method to build skis and snowboards? obviously with a slightly more complex core
Yes certainly as long as the design is adapted to suit the use as a snowboard or ski. You will want to tailor the core and skins to suit how much flex or stiffness you need for that specific application.
Not that I know of but it might be worth asking Entropy Resins directly. We have a special version that we developed in collaboration with them for our particular market (and application) but they are an innovative company and they may have other products with higher HDTs that I'm not aware of.
how the resin will react with wool? cotton? or materials found in sport socks - like Polyester (Coolmax), Polyamide (Nylon), Elastomero (Lycra)? will them make a decent bond, a decent structural rigidity? thank you very much! you have... GREAT videos!! ;-) best regards from Bucharest, Romania!
We have not experimented with any modern clothing fibres. We suspect that for many, the resin would wet out and cure in the normal sense, however the structural benefits would only really be found out from experimentation as it is not something we have seen before.
Of all the things you mentioned, only polyester would be worthwhile to use. Everything else either has too low tensile strength (wool, cotton) or stretches too much (nylon, lycra). The best materials on a weight, and price, to strength ratio are S-glass fiberglass and basalt. Basalt is a bit more environmentally sustainable than S-glass. But they don't have the stiffness strength of carbon fiber.
not sure if carbon fiber is the way to go all the time. For lonboards you usualy want a certain degree of bending. So if youre not 150kg youd propably prefer a glasfibre longboard.
It also depends on the other materials used. In this case, the Flax does not offer a lot of stiffness to the laminate so balancing it out with the stiffer carbon fibre probably means overall the balance works out about right for many cases. The finished longboard handled well from our own riders perspective.
Yes, I see no reason why not. If this was critical composites (aerospace, motorsport etc.) then you might worry about using paints on reinforcements and how it might affect the bond of the resin but for less critical applications like this it's fine to be a bit more creative.
Hello guys from @Easy Composites Ltd. I have a few questions if you don't mind answering them and if you find the time for it. I'm planning to make a downhill/race longboard from comoposite materials. I already own one but it's wooden, heavy, used and damaged. I plan to make a mould from it with concreate and cover the mould with fibreglass to make a good surface finish for release agent. I want to use Airex C70 pvc 5mm foamcore, some Unidirectional carbon and maybe +-45 carbon or unidirectional stripes running in X-pattern for torsonal ressistance because its very crucial for downhill racing and finally cover that up with some classic carbon fibre. But here is the thing. I have no idea what csm/weight carbon fibre to get, so it is still light and very sturdy and not a bit flexy. Can you please give me some ideas? I would be very very thankful. LOVE the videos btw. Keep them coming. Thanks
typically many people would go for a 2/2 twill fabric at 200gsm which is roughly 0.25mm thick per layer. You could follow a similar layup as in the video and replace the Flax Fibre with 2 or 3 layers of the 200gsm carbon cloth. Ultimately your design might vary depending on how strong you need it to be and with a thinner core perhaps more layers compared to ours but that should give you a rough idea to start from.
+David Stevens (davro) Thanks David. We like your videos too. Actually, the CLV really is a nice resin to use with good mechanical properties (as well as the environmental credentials).
Great explanation and video editing. I have a question: Could i use a full(uncut) 9mm baltic birch plywood as core material but with holes drilled so resin could soake in?
I see no reason why that wouldn't work. You might want to score between the holes on the bottom side to help give the resin more paths once it reaches the bottom layer.
Can you explain me why most people is usin a press for making the shape of concave and convex if is easy by this way? which way is better? thank you so much for sharing knowledge!!
Most people aren't using this combination of materials. The vacuum bag does the same job of the press but in a one off DIY format in this case and still allows us to do the resin infusion.
+easy composites I already went to your website before writing that comment and found there two categories of carbon fiber to be chosen so I got confused with that. So now if I order the flexible one I will be able to mould it in any shape and it will be durable right
+saurav sen; Ahh, I understand now. To make quad-rotor frame parts you would need our rigid, cured carbon fibre sheet as listed here: www.easycomposites.co.uk/#!/cured-carbon-fibre-products/rigid-carbon-fibre-sheet/Prepreg-Carbon-Fibre-Flat-Sheet.html
I just saw that the Biotex Flax fiber is no longer available in your store, what other material can I use to make this project? I'm building an electric longboard and I'm really interested in using this formula to make the deck. I hope you can help me. And thanks for the video and the channel, the tutorials are fantastic!
Hi Felipe, the manufacturers of the 'Biotex' flax fibres have discontinued some of the fabrics but others are still available and going strong. The 4/4 hopsack (used in this video) is no longer available but a 400g 2/2 twill fibre is still available and would have almost identical mechanical properties. Here's a link: www.easycomposites.co.uk/#!/fabric-and-reinforcement/natural-flax-and-jute-fibres/dry-flax-and-jute-fibres/flax-22-400g.html We also have a new unidirectional flax material which would work very well for adding longitudinal stiffness to the board, you'll find that one here: www.easycomposites.co.uk/#!/fabric-and-reinforcement/natural-flax-and-jute-fibres/dry-flax-and-jute-fibres/flax-unidirectional-150g-180mm-Wide.html, it's also extremely reasonable on price. I hope this helps.
Yes, in theory, you could build a stack of materials to replace the core around the perimeter (much like we do in our bonnet/hood making tutorial); as long as you use a woven material, rather than UD, then it should infuse without a problem.
Would it be possible to infuse some electrically conductive wires into the board for an electric skateboard or is the SuperSap and Carbon Fibre electrically conductive itself?
+Tony Lorentzen Epoxy resin isn't electrically conductive but carbon fibre is so it is possible to achieve conductivity through the laminate (although not in a perfect sense owing to insulating properties of the resin) so it depends on what level of conductivity you need and the direction you need it in; carbon will only conduct down the length of the fibres in a laminate like this. If you do need to lay conductive wires in then you could certainly do so.
@@easycompositestv Make those "more useable" examples help to spread the composite world to other consumers. You can make other videos like an rc boat or a small real boat and other in a serie of videos will be great and I bet you will sell more with those examples. 😉
I have experimented with vacuum clamping wood to laminate it. A lot of times when you pull the vacuum, water vapor comes off of the wood, making it hard to hold a steady vacuum. Have you ever had this problem when using a wood core? How do you deal with it, or did you dry the wood beforehand somehow?
@@easycompositestv thanks. I have seen it happen with seasoned wood in the sense that it sat around in my garage for a long time. But I guess it was not dry enough. Anyway thanks for all the great videos.
@easycomposite thanks for a nice video. Something caught my attention. On your web page, it says 600 gsm for UD fiber and 300 gsm for biaxial fiber. But in the video, the biaxial fiber looks much thicker. Could there be confusion in the numbers?
Actually hollow wouldn't be possible without making it in two halves but you could use a very low density core, that would pretty-much behave like it's hollow and be a whole lot simpler.
+Daniel Malcolm: Well, anything's possible! - You'd need to make the ball in two halves and bond them together (or some other variation on where the split is - but you'd certainly need two parts, in some way). I'd probably suggest making the two halves have a return flange on them and then you could use these flanges to bond the two halves together (gives you a good surface area for the bond). This does mean that each half does itself need to be a split mould but it's worth it in order to give you solid surface that can be bonded together to make the finished shape.
The wood strips were just cut from reclaimed pallet wood, the actual size does not matter too much as long as they aren't more than around a few cm across and are bonded with the slight gap to allow resin flow.
@@easycompositestv Hi again, sorry, I've been checking in your web page that there's discontinued the supersap resin, can I use the IN2 resin?, also could I use kevlar for reinforcement to gain torsional stiffness? thank you.
After seeing this I’m thinking about making a modeled seat for a sports wheelchair that I use for tennis, basketball and AFL(Australian Football League). Would that be hard to make for someone that hasn’t done it before? And what would I need to do this? Thanks
Hi Jason, well anything for the very first time often involves making a few mistakes. However, hopefully as you can see from the video the process can be broken down into individual, achievable steps and is quite possible to follow without prior experience. We'd always recommend starting with simpler projects or even just creating small test panels whilst you learn the process and find your feet but you might well find you really enjoy the learning process and then get a great result at the end of it. Good luck.
Easy Composites Ltd I am a cabinetmaker, I’ve built two street machines and build,tune and race slot cars. I am a hands on person that will give anything a go. Thanks
I was thinking about making a carbon fiber deck for an electric longboard. Do I need to install a wood or foam core for the carbon fiber to be strong enough to stand on? Can I make a carbon fiber deck without a core? How thick does it need to be so it wont break?
I've seen some dudes use a foam core. I'm pretty sure it held up well. A coreless skate deck? Sounds interesting. Make a mold for it man. Try it, and post the results.
Flash Nova yes, you can make a skateboard deck without a wooden or foam core. However, you will need to use more plies; somewhere around 17-20 depending on what modulus carbon you use and the fabric thickness. Your best best is to use 12 or so plies of uni (0°), 4 plies of biaxial (+45°/-45°), and a few plies of uni at 90°.
Depends whether you're referring to just the materials used in the board (probably about £50 for the carbon fibre, flax and resin) or all of the tools, equipment, vacuum pump, the former etc., in which case you're looking at more like £350.
+saurav sen Quadrotor frames are made using standard carbon fibre and epoxy laminates. You want them to be rigid, that allows them to be light and still have the right performance and characteristics. Often of course, people use ready-made tubes and sections - we stock a range of carbon fibre tubes, sheet, angles and box section that can be used to make quad frames on the www.easycomposites.co.uk website.
not being in the business and just wanna learn about resins & reinforcement, i asked a stupid question. yup, the glue is on the grip tape's bottom already. sorry.
+Joe Thomas : If you want to get a release of MDF then you'll need to use LOTS of coats of Shellac Sanding Sealer (available from timber merchants/furniture restorers/hardware stores) which will allow you to properly seal and polish the porous surface of the MDF. After this, it's possible to use mould release wax or chemical release agent to get a release from MDF.
Is it possible that you list everything you used here? (Except the mould material) and it would be even better with the price per meter or yard of the different fibers used in the tutorial. I was browsing on your website and I was a little overwhelmed by how much stuff about carbon and other related stuff (which is good) that I lost track of what I was doing (because I was going back and forth between this video checking everything out and your website)
Please see this page; all materials are tagged and the there’s a detailed write up: www.easycomposites.co.uk/learning/resin-infused-skateboard-sustainable-composites
+sean avery : Yes, that's a possible project for the future. I'm not sure if you're thinking small scale fan blade like a prop on a quadcopter or large scale like a wind turbine blade but either way, these are both possible projects we could cover.
+davidgruty 80-120 sounds about right (for a pair) when you order just 1 or 2 metres of fabric at a time and you'll have quote a bit of leftover material. If you were making these in quantity then the material cost per board might be down at more like £40/30 euro per board.
how do the timber strips not warp after you’ve cut them? i tried to rip down some pallet timbers and they were so bent that they were impossible to use!
We just didn't have that problem with the timber we used. Maybe it's just down to the pallets you're using and how they've been stored, especially how dry they are or if they've been subjected to much 'weather'. Maybe try again with some different pallets :)
Yes, we sell all of the composite materials and the equipment. Anything that's specifically 'skateboard' related (like the trucks, wheels and grip tape) you can source from any many different suppliers. Here's a link to a list of all the tools and materials we used: www.easycomposites.co.uk/#!/composites-tutorials/resin-infused-skateboard-using-carbon-fibre-flax-and-bio-resin
Carbon fibre but no core material? - Just sold carbon fibre? - Probably you'd need about a 5mm laminate which would mean a lot of layers of carbon fibre (example 7 layers of 650g) but the layers of carbon fibre in the middle of the laminate would not really be doing much which is why we tend to use core materials.
It would depend on the wood. Traditional wood stabilisation is not done this way although the principles of working under a vacuum to remove the air and thus allow the resin to displace where the air was is similar. Typically that is done in a vat of slow curing resin rather than a vacuum bag approach.
Yes, full list of the products used in the video, along with links to buy, on this page: www.easycomposites.co.uk/#!/composites-tutorials/resin-infused-skateboard-using-carbon-fibre-flax-and-bio-resin
Hi Randy, we don't actually make or sell the longboard however we do sell all of the materials and equipment you see used in the video. You can find a fill list of materials here: www.easycomposites.co.uk/#!/composites-tutorials/resin-infused-skateboard-using-carbon-fibre-flax-and-bio-resin
+Mohamed Khlifi Not really: a flooring resin is designed for a different purpose to an infusion resin. You'll find a flooring resin too viscous (thick) and mechanically it won't have the right performance.
I'm not sure how to give you a measurement on that but you can see us having a ride on it at the end of the video where the flex in the board can be see, I guess.
The one we used in this video was a 400g plain weave flax. That exact one is no longer available from the manufacturer but we have a similar flax product (from the same manufacturer) here: www.easycomposites.co.uk/#!/fabric-and-reinforcement/natural-flax-and-jute-fibres/dry-flax-and-jute-fibres/flax-22-400g.html
I love your channel and i want to do my own longboard but i am french so i dont understand All so can you add french subtitle please or just writen english subtitle to help us thanks
Yes, we'll definitely. I'll catch up with our team and make sure we get English CC subtitles added to this which should make it easier for you to view a French translation.
Don’t you get carbon splinters the way your run your hands across the carbon fiber like that? I just got done working with MD Carbon fiber bare handed and I have Micro splinters.
OK, no problem. Yes, you can use it in just the same way that you can use a conventional epoxy so carbon fibre (as shown in this video), glass fibre, natural fibres - they're all fine. As for urethane - are we talking foam, rubber or plastic and do you want it it bond or just not dissolve/attack it? - Epoxy won't attack urethane, the bond strength will depend on surface prep and the format of the urethane.
It also helps when drilling through composites to start out with the drill in reverse which prevents the bit from ripping the fibers. After drilling through the first layer or two, return the drill to normal drive but don't drill all the way through the other side. As the bit starts cutting though the opposite side of the panel reverse the drill again and cut all the way through the panel. This will leave you with a very clean hole through both sides of your panel.
Thanks for the comment James, that all sounds logical and good advice.
I wonder if a drill bit modified for soft metals would also work?

Hey, I love your video. Can I use it for my compilation? I will give you full credits.
Great to see the use of eco resins. What kind of temp can the eco resin handleBefore going soft.
The HDT of the SuperSap CLV is 48°C so we would recommend keeping it below that temperature.
The SuperSap CLV has a Tg of 62'C therefore it's OK up to 62 but after that it would be losing its mechanical properties.
Ok thanks for that.
Are they working on a product with a higher HDT
Not that I know of but it might be worth asking Entropy Resins directly. We have a special version that we developed in collaboration with them for our particular market (and application) but they are an innovative company and they may have other products with higher HDTs that I'm not aware of.
Forged CF/Kevlar trucks would be a good build.

Wouldn't the flax be essentially useless to the strength of this board since the cf is so much more stiff and taking up all the load?
Although the carbon adds a lot of stiffness, the flax does still add some.

+easy composites I already went to your website before writing that comment and found there two categories of carbon fiber to be chosen so I got confused with that. So now if I order the flexible one I will be able to mould it in any shape and it will be durable right
+saurav sen; Ahh, I understand now. To make quad-rotor frame parts you would need our rigid, cured carbon fibre sheet as listed here: www.easycomposites.co.uk/#!/cured-carbon-fibre-products/rigid-carbon-fibre-sheet/Prepreg-Carbon-Fibre-Flat-Sheet.html
I just saw that the Biotex Flax fiber is no longer available in your store, what other material can I use to make this project? I'm building an electric longboard and I'm really interested in using this formula to make the deck. I hope you can help me. And thanks for the video and the channel, the tutorials are fantastic!
Hi Felipe, the manufacturers of the 'Biotex' flax fibres have discontinued some of the fabrics but others are still available and going strong.
The 4/4 hopsack (used in this video) is no longer available but a 400g 2/2 twill fibre is still available and would have almost identical mechanical properties. Here's a link: www.easycomposites.co.uk/#!/fabric-and-reinforcement/natural-flax-and-jute-fibres/dry-flax-and-jute-fibres/flax-22-400g.html
We also have a new unidirectional flax material which would work very well for adding longitudinal stiffness to the board, you'll find that one here: www.easycomposites.co.uk/#!/fabric-and-reinforcement/natural-flax-and-jute-fibres/dry-flax-and-jute-fibres/flax-unidirectional-150g-180mm-Wide.html, it's also extremely reasonable on price.
I hope this helps.
Hello Easy composites, is it posible to put reinforcement in the sides of the board? Will I be able to infuse that reinforcement too?
Yes, in theory, you could build a stack of materials to replace the core around the perimeter (much like we do in our bonnet/hood making tutorial); as long as you use a woven material, rather than UD, then it should infuse without a problem.
ABSOLUTELY COOL
Would it be possible to infuse some electrically conductive wires into the board for an electric skateboard or is the SuperSap and Carbon Fibre electrically conductive itself?
+Tony Lorentzen Epoxy resin isn't electrically conductive but carbon fibre is so it is possible to achieve conductivity through the laminate (although not in a perfect sense owing to insulating properties of the resin) so it depends on what level of conductivity you need and the direction you need it in; carbon will only conduct down the length of the fibres in a laminate like this. If you do need to lay conductive wires in then you could certainly do so.
U can do it but you need copper filets
Great video!
Thanks Ruda.
@@easycompositestv Make those "more useable" examples help to spread the composite world to other consumers. You can make other videos like an rc boat or a small real boat and other in a serie of videos will be great and I bet you will sell more with those examples. 😉
As it is a bio resin does it make it safer to use with animals? I was thinking of making a waterfall for a vivarium.
Being a bio resin doesn't change the cured safety of the resin. Once fully cured, epoxy should be very stable and safe.
I have experimented with vacuum clamping wood to laminate it. A lot of times when you pull the vacuum, water vapor comes off of the wood, making it hard to hold a steady vacuum. Have you ever had this problem when using a wood core? How do you deal with it, or did you dry the wood beforehand somehow?
Generally we recommend using kiln dried or other forms of seasoned and dried wood to minimise this.
@@easycompositestv thanks. I have seen it happen with seasoned wood in the sense that it sat around in my garage for a long time. But I guess it was not dry enough. Anyway thanks for all the great videos.
@easycomposite thanks for a nice video. Something caught my attention. On your web page, it says 600 gsm for UD fiber and 300 gsm for biaxial fiber. But in the video, the biaxial fiber looks much thicker. Could there be confusion in the numbers?
Hi, no there's no confusion the aerial weights of the fibres are calculated per SQM so although the biax looks heavier it actually isn't.
How can you make this skateboar hollow? Is there anyway to do a resin infision but hollow? Obusly with no holes on the surface.
Actually hollow wouldn't be possible without making it in two halves but you could use a very low density core, that would pretty-much behave like it's hollow and be a whole lot simpler.
Love the videos guys, is it possible to make a sphere/ball (50cmD) with these materials/processes? any tips about how to go about it?
+Daniel Malcolm: Well, anything's possible! - You'd need to make the ball in two halves and bond them together (or some other variation on where the split is - but you'd certainly need two parts, in some way). I'd probably suggest making the two halves have a return flange on them and then you could use these flanges to bond the two halves together (gives you a good surface area for the bond). This does mean that each half does itself need to be a split mould but it's worth it in order to give you solid surface that can be bonded together to make the finished shape.
Never intended to make a skateboard.. Mastered it nonetheless..i'd love to ride that puppy... :)
Hi, May I ask you, what are the wide and deep of the strip wood in mm? Thank you
The wood strips were just cut from reclaimed pallet wood, the actual size does not matter too much as long as they aren't more than around a few cm across and are bonded with the slight gap to allow resin flow.
@@easycompositestv Hi again, sorry, I've been checking in your web page that there's discontinued the supersap resin, can I use the IN2 resin?, also could I use kevlar for reinforcement to gain torsional stiffness? thank you.
Great channel.
Nice & Thanks :)
After seeing this I’m thinking about making a modeled seat for a sports wheelchair that I use for tennis, basketball and AFL(Australian Football League).
Would that be hard to make for someone that hasn’t done it before?
And what would I need to do this?
Thanks
Hi Jason, well anything for the very first time often involves making a few mistakes. However, hopefully as you can see from the video the process can be broken down into individual, achievable steps and is quite possible to follow without prior experience. We'd always recommend starting with simpler projects or even just creating small test panels whilst you learn the process and find your feet but you might well find you really enjoy the learning process and then get a great result at the end of it. Good luck.

I was thinking about making a carbon fiber deck for an electric longboard. Do I need to install a wood or foam core for the carbon fiber to be strong enough to stand on? Can I make a carbon fiber deck without a core? How thick does it need to be so it wont break?
I've seen some dudes use a foam core. I'm pretty sure it held up well. A coreless skate deck? Sounds interesting. Make a mold for it man. Try it, and post the results.
Flash Nova yes, you can make a skateboard deck without a wooden or foam core. However, you will need to use more plies; somewhere around 17-20 depending on what modulus carbon you use and the fabric thickness. Your best best is to use 12 or so plies of uni (0°), 4 plies of biaxial (+45°/-45°), and a few plies of uni at 90°.
Great video and we want to start making some carbon fiber products here but dang.. the price is out there. How much did this long board cost to make?
Depends whether you're referring to just the materials used in the board (probably about £50 for the carbon fibre, flax and resin) or all of the tools, equipment, vacuum pump, the former etc., in which case you're looking at more like £350.
Excellent video. Cheers. :-)
Which carbon fiber to use rigid or flexible in order to make quadrotor frame +easy composites
+saurav sen Quadrotor frames are made using standard carbon fibre and epoxy laminates. You want them to be rigid, that allows them to be light and still have the right performance and characteristics. Often of course, people use ready-made tubes and sections - we stock a range of carbon fibre tubes, sheet, angles and box section that can be used to make quad frames on the www.easycomposites.co.uk website.
hi again!
how did you fix the griptape on the board, what glue so that it fixes well over the epoxy resin?
thank you very much!
best regards,
Mircea
not being in the business and just wanna learn about resins & reinforcement, i asked a stupid question. yup, the glue is on the grip tape's bottom already. sorry.
Wow😍
Well done
Can the release agent be applied directly to an MDF mold?
+Joe Thomas : If you want to get a release of MDF then you'll need to use LOTS of coats of Shellac Sanding Sealer (available from timber merchants/furniture restorers/hardware stores) which will allow you to properly seal and polish the porous surface of the MDF. After this, it's possible to use mould release wax or chemical release agent to get a release from MDF.
I love it!!!
Good stuff Carlos, glad you likes it.
what was the cost of this longboard ? i mean all the materials
great video and i like the bio resion , great feature ! love it
Look on their website how much the Carbon fiber and epoxy cost
Is it possible that you list everything you used here? (Except the mould material) and it would be even better with the price per meter or yard of the different fibers used in the tutorial. I was browsing on your website and I was a little overwhelmed by how much stuff about carbon and other related stuff (which is good) that I lost track of what I was doing (because I was going back and forth between this video checking everything out and your website)
If you watch the video through the Learning Centre on our website, it lists all the products used in the video.
@@easycompositestv Thanks, I'll go and check out now
Didnt tag the material list in the description
Please see this page; all materials are tagged and the there’s a detailed write up: www.easycomposites.co.uk/learning/resin-infused-skateboard-sustainable-composites
It's amazing channel!

hi any chance you could make a fan blade as I would like to make sum for a project.
+sean avery : Yes, that's a possible project for the future. I'm not sure if you're thinking small scale fan blade like a prop on a quadcopter or large scale like a wind turbine blade but either way, these are both possible projects we could cover.
Very interesting.
it would be nice to know the total cost for this?
If you have to order the stuff in that little amuonts, It could be about 80-120 € for two Boards.
+michi derkinderen just the Material for the board.
+davidgruty 80-120 sounds about right (for a pair) when you order just 1 or 2 metres of fabric at a time and you'll have quote a bit of leftover material. If you were making these in quantity then the material cost per board might be down at more like £40/30 euro per board.
how do the timber strips not warp after you’ve cut them? i tried to rip down some pallet timbers and they were so bent that they were impossible to use!
We just didn't have that problem with the timber we used. Maybe it's just down to the pallets you're using and how they've been stored, especially how dry they are or if they've been subjected to much 'weather'. Maybe try again with some different pallets :)
*Lol that separated UK and EU flag on the end :O*
Brexit!
I would like to make these at home, do you guys sell all the items used in this video as a package?
Yes, we sell all of the composite materials and the equipment. Anything that's specifically 'skateboard' related (like the trucks, wheels and grip tape) you can source from any many different suppliers. Here's a link to a list of all the tools and materials we used: www.easycomposites.co.uk/#!/composites-tutorials/resin-infused-skateboard-using-carbon-fibre-flax-and-bio-resin
Thanks for the response! If I wanted to make this with just carbon fibre, how much layers would it need?
Carbon fibre but no core material? - Just sold carbon fibre? - Probably you'd need about a 5mm laminate which would mean a lot of layers of carbon fibre (example 7 layers of 650g) but the layers of carbon fibre in the middle of the laminate would not really be doing much which is why we tend to use core materials.
Sorry I didn't mention it, I would make a foam core but I guess that wouldn't give much strenght
Is it necessary to have the fusion mesh or is just the spiral enough for this long shape? I'm working on a car spoiler
Is it possible to use this method to infuse resin into a wood laminate?
It would depend on the wood. Traditional wood stabilisation is not done this way although the principles of working under a vacuum to remove the air and thus allow the resin to displace where the air was is similar. Typically that is done in a vat of slow curing resin rather than a vacuum bag approach.
great stuff :)
Is there a list of things that he used?
Yes, full list of the products used in the video, along with links to buy, on this page: www.easycomposites.co.uk/#!/composites-tutorials/resin-infused-skateboard-using-carbon-fibre-flax-and-bio-resin
Is these things expensive
Hi Randy, we don't actually make or sell the longboard however we do sell all of the materials and equipment you see used in the video. You can find a fill list of materials here: www.easycomposites.co.uk/#!/composites-tutorials/resin-infused-skateboard-using-carbon-fibre-flax-and-bio-resin
very nice

Can I use a floor resin with the carbon?
+Mohamed Khlifi Not really: a flooring resin is designed for a different purpose to an infusion resin. You'll find a flooring resin too viscous (thick) and mechanically it won't have the right performance.
how much is the flex of the board ?
I'm not sure how to give you a measurement on that but you can see us having a ride on it at the end of the video where the flex in the board can be see, I guess.
bravo
what natural fibre did you use? where do I find it?
The one we used in this video was a 400g plain weave flax. That exact one is no longer available from the manufacturer but we have a similar flax product (from the same manufacturer) here: www.easycomposites.co.uk/#!/fabric-and-reinforcement/natural-flax-and-jute-fibres/dry-flax-and-jute-fibres/flax-22-400g.html
I love your channel and i want to do my own longboard but i am french so i dont understand All so can you add french subtitle please or just writen english subtitle to help us thanks
Yes, we'll definitely. I'll catch up with our team and make sure we get English CC subtitles added to this which should make it easier for you to view a French translation.
Don’t you get carbon splinters the way your run your hands across the carbon fiber like that? I just got done working with MD Carbon fiber bare handed and I have Micro splinters.
Once fully sanded smooth you should not get any splinters.
Is it cool to use on urthane?
Do you mean the resin or the infusion process or the fibre?
+Easy Composites Ltd oh! Sorry for being unclear. The new bio resin. Is it safe on urethane? And is it ok to use carbon fiber with it? Or fiber glass?
OK, no problem. Yes, you can use it in just the same way that you can use a conventional epoxy so carbon fibre (as shown in this video), glass fibre, natural fibres - they're all fine. As for urethane - are we talking foam, rubber or plastic and do you want it it bond or just not dissolve/attack it? - Epoxy won't attack urethane, the bond strength will depend on surface prep and the format of the urethane.
