@Dryzaum though is necessary to say that titanium oxidizes on air at 660ºC and reacts with nitrogen over 800ºC, that's why titanium is not used in turbines blades of aircraft, neither on combustion chambers or in the heat part of turbochargers of vehicle, For that purpose are used cromiun-nickel, niobium-molibdenum, carbon/boron cerments etc. Titanium is used in compressor section and as structural support.
i agree with you on one point! but if you wanna see something about carbon, check the video: megafactories lexus lfa! you see how they layer it and learn a lot about it!
it helped in my report in materials engineering. It's not boring, try to explore further material from carbon fiber. Your may not be interested but see automobile parts are made from carbon fiber. It's amazing how the strength of materials come into a not expected one.
@AZURA888 So the exhaust dont reach that levels of temperature? Or that ''titanium exhaust" that they use in the Zonda, for instance, is a blend of titanium with something else?
@00Mass00 imm, which is the time it takes to transform some quantity of polyacrilonitrile into carbo fiber through heat?, hours, weeks, months?. The process seems to be simple but slow. Thomas Alba Edison created some rough type of carbon wire. 180ºC, 240ºC, 1000ºC on Argon atmosphere, 2400ºC, 3000ºC.
I know what you mean, I certainly would have respect to approach a machine with a tie. But it isn't like he is bowing towards the machine. ;-) I think he knows those machines very well.
well unless you have a huge oven home and vac bags you can't do the repair home... and as for the look of the CF weave will be impossible to match but if the car has paint on it you will never be able to tell the difference... and as for the strength the CF will retain all of its strength after a repair just like glass fiber... and just like glass fiber you don't need to replace the whole part but you can patch it up then apply filler were needed and paint
@00Mass00 Carbon fiber gets it's name from the fact that it is mostly composed of carbon atoms. Carbon is an element (atomic number 6), it's name comes from the Latin "Carbo", meaning coal. Carbon fiber does not carbonize, because it already is carbon. (Carbonization is when an organic material containing carbon is heated and releases that carbon.) Carbon fiber sublimates (transitions from a solid directly to a gas) at 3642ºC. Some carbon composites are heat resistant (carbon-carbon) some aren't
Why isn't it cheaper to do everything in one area from precursor to sheets of carbon fiber? All that shiping japan to the uk to germany must be expensive?
First off if it isnt about hardness but about tensile strength, density and stiffnes. As for those regular carbon fiber excels that of glass fiber by about 20%, is lighter by 20% or more and is 4 times stiffer (elongation over stress). There is a good reason for using it.
carbon fiber repair is done similar to glass fiber so a specialist is not required... and repair cost may not be as expensive as you think but it still is costly... and when it comes to safety CF is much better cause in NCAP rating the CF cars are so strong one car can be used for all the test where as steel cars can only stand up to one test before being written off....
@Nairuulagch can't be burned, in the process the fiber is heated and quenched at 3000ºC, so if you put a zippo to a wire it turns red but doesn't burn because is already burned, more heat 4800ºC? it sublimates.
+abdollar34 Its called a polymer spinning process. Where the polyacrylonitrile (PAN) is extruded through a spinnerete and stretched through several drives to produce the required dpf of a fiber. these strands you speak about depends on the spinnerete i.e; a single yarn may contain 3000, 6000, 12000 filaments. The final yarn you get is called SAF( special acrylo fiber).This SAF is subjected to oxidation and rest is shown in the video. Finally you get the CF
+Manu Prasad +JL S great answers thx guys! I was irritated because I thought the white precursor which is shown in the creel area is sth like a flat tape thing that is turned into thin filaments and tows later in the process...
The biggest issue with using carbon fibre components like masts and booms for racing yachts is that the component explodes when its resistance to stress or impact is exceeded and carbon shards explode everywhere. How to contain that is a big challenge.
ok there trying to be as green as they can during manufacturing , i kindah wonder how long it takes for carbon fiber to desolve or if its possible to reuse the material like you can aluminium or metal
+watahyahknow This is not a foundry. They do not have "dirty processes" in their facilities. The only reason (none really) they talk about a "carbon foot print" (which nobody has ever seen---like a real "Bigfoot" foot print), is because their processes take a lot of energy,---that wind mills and solar can not possibly provide (they had to go hydro---and used that for their relocation, and probably lucky they found one). I think it is time for the citizens of the world to wonder,--"Is this green movement thing really about saving nature, or destroying our wealth making capabilities?" If you compared the decline of nature to the decline of the global economy for any citizenry in the world (over the last 40 years)--which is worse? Have you ever seen a dictatorship who let their citizenry get wealthy with a free market?
Have to first remove the resin with pyrolitic decomposition (basically vaporizes all the organic resin in an oxygen free atmosphere then burns them to vaporize the resin of the next piece of carbon fiber) It is then shredded. It is then only used to reinforce plastics or concrete because it's is no longer continuous lengths
When will they understand we don't want a carbon fiber part that's as strong as steel, but a part that is stronger than steel? Fex, put a few extra layers in that roof and sell it as a safety-feature (no pole is going to come through that roof, impaling your loved ones, if you land upsidedown at the side of the road). But a good video nonetheless! Very clever that guy who thought out that robot that makes the carbon composite roof, get him to think up robots that make other parts aswell!
@Nairuulagch Carbon fiber can not burn.. it only carbonizes thats where it gets his name from :) thats whats gives the material its great stiffness and strength.. however it takes about 3000 degrees to do so, and a lot of time(specially high modulus carbon).. that's why its so expensive
Why is it necessary to to send the fibres for such long runs whether vertical or horizontal. Obviously there must be a reason but it can't just be tension eh?
To make something out of a steel or aluminum alloy, you use perhaps two or three automated process. Carbon fibre manufacturing uses at least half a dozen individual process plus a huge amount of manual labour during set-up and transition between these processes. It takes a 45 minutes to weld an Aluminum bicycle frame together by hand. It takes several hours just to lay up the layers of carbon fibre in a mold to make a single tube of a bicycle frame, plus all of the work done to make those sheets
Oxidising from Polyacrylonitrile to the carbon fiber precursor, it's done by heating in an oven. Then the precursor is heated in a vacuum oven at a much higher temperature to make the final CF product (done in a vacuum otherwise the CF would oxidise further and just get turned into CO2 and ash)
Mario Trevino-Gonzalez your logic: I just destroyed 3 of my 4 neurones figuring out how to post a comment on youtube. Now I should destroy the other one attempting to contemplate how another human's mind operates.
I'm absolutely amazed at the lack of human intervention in the entire process. I wonder how many human actions were left out because they don't look as good on camera...
would you want to move a roof part from one spot to another all day every day? robotics is more precise and efficient, also cheaper. that's just how it goes.
Uh. What? I was just commenting on the impressive degree of automation. Not sure why you have a hard-on for people who you perceive to be anti-automation. Go argue at a wall, or something, it will be more interested.
Such a sick process and overall its just amazing in general that they can actually do this sort of thing
love this video. for me the best part is the fibres progressively getting darker as the move through the rollers :D
Really interesting and seems even more detailed than what Discovery shows on the topic.
this video is a must for students who are learning how to manufacture products of composites..

Really cool.
Oxidizing means removing the electrons or decreasing the electropositive element or radical of the material
Thank You For The Information
Greetings Toyota,
just perfect
Nice video..thx
AWESOME !!!!
Fascinating! Thank you for sharing this with the public. It sparks my imagination! Can I assume that the AC45 boats get the carbon from here?
it helped in my report in materials engineering. It's not boring, try to explore further material from carbon fiber. Your may not be interested but see automobile parts are made from carbon fiber. It's amazing how the strength of materials come into a not expected one.
The best thing in this video was the robotic arms in the end , they seem to be more complex then the carbon fibre ...
Super Strong Hair!
Thank Sir
@AZURA888 So the exhaust dont reach that levels of temperature? Or that ''titanium exhaust" that they use in the Zonda, for instance, is a blend of titanium with something else?

8:24 brave Germany, wearing a "tie" and standing next to a rolling machine.
I know what you mean, I certainly would have respect to approach a machine with a tie.

so when on sale we will see first fully carbon fibre BMW? seems like serious preparations are very advanced...
Nice focus on carbon footprint ;-)
@Nairuulagch dude a lot of exhaust systems are made from carbon
thank you for watching :-P
This reminds me of the droid factories in star wars lol.. they even make all the same sounds too lol
What makes the color change? They were white at first beginning.
guess i missed it, but why is it pulled over such long distances

Hi are you carbon expert?
Thanks for the explanation. Do you are Chemical engineer PhD. ?
this is good vidio.
Why isn't it cheaper to do everything in one area from precursor to sheets of carbon fiber?
All that shiping japan to the uk to germany must be expensive?
Nothing like a Dodge commercial in the middle of a BMW corporate video.
the manager is a bit funny how he finishes his sentences :D
the carbon fiber strands are weaved by many different companies as in Hexcel, Sigmatex and other
Duane Bowen hi can i ask you a question?
wow, i didnt know anything like that was an hour and a half drive from here. cool, wonder if i can get some blems lol
nice

I love carbon fiber interior.
About 2013 with the introduction of i3.
this video was as exciting as watching grass grow.

I wonder why they used plain weave instead of uni directional weave, plain is not as strong.
Where in japan?
@Nairuulagch can't be burned, in the process the fiber is heated and quenched at 3000ºC, so if you put a zippo to a wire it turns red but doesn't burn because is already burned, more heat 4800ºC? it sublimates.
AZR NSMX1 have you seen the video of burning carbon fiber rod?
At what point of the process are carbon fiber strands bundled into rovings?
Can anyone tell? Is it during the oxidation?

bmw m5 roof brought me here, sick!
heppolt wind turbine the cool thing
It looks like a mix of textile and steel plants
yeah

Does Carbotanium also do that?

cool wonder if that system uses a lot of energy though , it IS interesting to know it CAN be done though
watahyahknow Recycling doesn't use much energy (the removal of the resin is usually self-sufficient)

00Mass00 have you seen the vid of burning carbonfiber rod?
how many people does it take to operate the Carbon Fiber line.
Between 4 and 7.
I wanna buy one roll of cloth
Brilliant!
Why is it necessary to to send the fibres for such long runs whether vertical or horizontal. Obviously there must be a reason but it can't just be tension eh?
Oxidation and carbonization residence time to capture mechanical and physical properties.
@@josephstorrud8050 Thanks! I watched it again and they allude to that in the beginning
your right you dont work for lexus you only produce the power plant for them :D
German know their shit, precision and engeneering marvel!

Didn't know David Lynch did internal work
Why is this not done in Germany from start to finish??
Where are the workers?
Is it BMW policy not to look directly at the camera?
That would be unsettling
There are only clients on germany
I do this work...... Their plant is so much more high tech than ours.
0:03 Mr Freeze
why do they all look that nervous in this video?! and that second guy just creeps me out "THIS IS...."
if you crash your gonna have to buy new steel or plastic ones aswell, tho they are much cheaper.
So you got three competing materials in automotive manufacturing - carbon fiber, aluminium, and steel.
This guy looks so smart lol
Maybe stronger and lighter than steel yet very non resistant to heat, easily burns I guess.
Did anyone else fall asleep while watching this?
Yeah I did... didn't even make it half way through I dont think now i'm watching it again skipping through the parts that I think I watched.
Means you have been watching too much porn.
this guy's logic: spends almost 15 minutes watching a video just to complain about how boring it was..
mathlover101hotmail Not enough porn lol

Is that 48K tow? :O
Looks more like 50k
looks like the m3's roof :)
All that shipping must equate to higher cost of BMW cars.
From Japan to Seattle to Germany...
Presenter is so funny
The one thing i didnt see in the factory, was people, where is all the workers? i only seen one.
Will ferrer is that you?
CHORISCOPIC
why color change? pag ang iron nahaluan ng oxygen, nag iiba ang kulay, prang kinakalawang. parang gnun dn yung concept nun.
Funny he says SGL is enraged about the release of the video, yet SGL has their own channel.... Hmm...
he looks like a super hero secs 1-5 XD
Moses lake..frickin funny..on the coat tails of boeing i guess..not airbus

Make me a bronze car
Why didn't they just buy from alibaba
50k in a strand?!?
I work at the plant
You are lucky
Carbon fiber composites are not harder but stronger(not the same!!)...
why so serious? the host i mean
Will Ferrell..??!
if he was an awkward and bad actor. wait
because it's raw footage, he didn't edit it, no music, no narrator, nothing
Carbon fibers are made in Washington, USA because electricity is cheaper?
Yup
im very surprised that bmw actually produce it internall from scratch, instead of buying it from a supplier
Sgl is their supplier of the raw tow
You mean video.
so fun to see germans speaking english.
what??? an carbon fiber roof without cooking in an autoclave???
