kinda makes me wonder why they don't make a tank/armored vehicle out of composite material like how kevlar protects humans..it would benefit in terms of reducing fuel consumption, heat signature as a result, and make the vehicle faster? to make it more defensible and evasive and stealthy
Indeed! It covered the non arts and crafts portion of the first semester of my degree in "Aerospace Composites Manufacturing" What is more impressive is that I didn't catch anything wrong or that was blatantly missed. (At least that could have been fit within half an hour that is...) The reverse of the Gellman amnesia effect I suppose. Rare that you find a summary video that actually does a good job on something you have quite a bit of knowledge on. Always a good sign when the creator talks about things you aren't as familiar with as well... I'm definitely going to be showing this video to several people. At the least I will show it to some high school students I mentor!
I have just rewatched it today. Amazing content, jaw breaking animation quality, you learn more in 20 minutes than hours of courses and internet digging. I am shameful that I can only buy you a pint but if a lot of people do the same, you will get an effective crowd patronage. Thank you for your work !
This is an excellent video, your animations are first class. I'd love to see a second part of this topic dealing with failure modes and adding more detail in the different manufacturing processes.
@@georgedreisch2662 interesting enough the space shuttle that burned up upon re entry was due to Nasa changed the ceramic heat tiles to carbon fiber ones and the carbon fiber ones cracked and broke
There's nothing wrong with using composites in compression, anyone can make a sh*t design out of any material and have it fail prematurely. Oceangate's management just had no idea what they were doing. That's why their lead engineer sued them. He knew it was going to fail because poor design decisions were being made. They cut corners (testing) and suffered the consequences.
I'm studying mechanical engineering + automation and industrial robotics here in Poland and I have to say THANK YOU for making all these vids and helping me and others to understand 'how stuff works'. Really appreciate the quality and effort you put in these
As the composite materials engineer from university, I have to say - this video is incredibly informative and accurate! Definitely would recommend it to students
I really appreciate these videos. I'm a recent mechanical engineering grad, and I've never worked with composites, but it's nice to know some of the theory as presented here. Your work is great
I'm blown away by the quality of the content! I've updated my university knowledge on composites, which I hadn't worked with for over a decade. It'd be amazing if this material was also in the form of notes or a presentation. The animations are gorgeous!
You guys are absolutely amazing and deserve more views...♥️ I am definitely recommending this channel to all my juniors who are pursuing an engineering degree. Keep it up 👏
I'm a brick and stone mason, learning about material science has always been a fascinating subject. There's quite literally endless combinations and geometries available, reminds me of fractals ..
It has been 5 years since I completed my B.Eng, and my greatest fear is that I would forget interesting topics due to lack of application in my current occupation. Your videos help serve as a quick yet effective recap of the theories I have spend months studying.
High quality information made seem simple. Wish if all the lessons were taught in this manner. Really enjoying the videos uploaded by efficient engineer. Appreciated the efforts put into every videos 😊
Great video, thank you, especially the first half. Maybe for other ideas explaining thermoplastics, RTM injection. Also on sandwich, core can also be metal. Applications for sandwich are also for acoustics attenuation. New types of reasearch include composite material built from additive material techniques (also working for metals) which brings a lot of new ideas to solve old issues
For the biomedical bonding to bone fast at 18:30, here in Australia about 20 years ago, we showed how coral knitted to bone and gave the new bone structures a strengthening shape. Lattice is the key word.
This is the best video on composite materials I have ever seen on UA-cam. There was a book called The Science of Strong Materials, or Why You Don't Fall Through the Floor. It was the best book that I ever read about composites. Additionally the first most interesting introduction to composites I heard years ago was on a series called Infinite Voyage, narrated by Leonard Nimoy. Composites, for most applications, are amazingly strong for their weight.
18:20 It's mentioned that magnesium implants don't need a second removal surgery as magnesium will biodegrade. But when we use a composite containing ceramic particles in magnesium matrix as said in this video, once magnesium degrades, won't these ceramic particles (as they are not biodegradable) act as foreign contaminants (or shall I say "pollutants") in our body? These have to be removed from our body, right? How is this done? I just am fascinated by this subject, but this aspect of these implants intrigues me. Am I missing something out? Any help will be appreciated. Thanks..
Excellent video! I encourage anyone watching this to get into the workshop and build some composite parts. Certain materials and design tools are financially out of reach for most of us, but with a relatively small investment you can make high quality vacuum-bagged carbon parts at home. There are tons of great videos and books out there to help out. You can--and should-- learn all of the theoretical side of composites, but there is no replacement for the understanding derived from making parts yourself.
00:05 Composite materials have transformed engineering problems and allowed development of materials with unique properties. 03:21 Fiber-reinforced materials have anisotropic properties and can be made strong in specific directions. 06:25 Different methods for manufacturing fiber-reinforced composite parts 09:38 Glass-fiber reinforced polymers have excellent strength-to-weight ratios. 12:37 Fiber-reinforced polymers have good corrosion resistance and dimensional stability, but are expensive and brittle. 15:21 Ceramic matrix composites have high temperature resistance and increased toughness with the use of fibers. 18:13 Composite materials offer improved properties and control over degradation rate 21:03 Composite materials and their applications
This has been one of the main reasons I Love composites! Especially when I was in highschool! This is also the best way to deploy graphene and carbon nanotubes, at least for now! The Damping Properties Is Especially Important in Aerospace and Eventually When We Build Megastructures in space! You Could Literally Design a Megastructure with All those Composites with Careful Placement, Giving You a Range of All The Properties You Need Spread Out, and with Other Properties Arranged in Different Configurations for Truly Incredible Abilities! I Had thought of those Honey Comb Stuctures, but Writ Large, and Everything Covered In either a Graphene Concrete Mix, Or Encasing Everything in a Graphene composite of sorts, at least in a Mega Structure.
But is a plastic manifold really a big deal? They have been used for the last, what? 30 years? and it’s not like they are exploding all the time…. I am pretty sure someone in the world has also had problems with leaking aluminium manifolds💁🏻♂️ Using low quality plastic is a different thing.
It's funny how much of this I knew from just knowing about how carbon fibers are used in sports equipment like hockey sticks. But this was a great video and I enjoyed it very much. Thank you for such a high quality video.
16:34 What the fibers are doing within the ceramic is something very similar to crazing right? Where in crazing there's plastic deformation that release energy by creating perpendicular gaps which help prevent crack propagation
Thanks for this interesting video! One remark: the disadvantages mentioned for CFRPs, such as low-temperature applications or joining difficulties, have been mitigated in the past decades by using thermoplastics and more advanced polymers.
One big drawback that you overlocked is reparability, though it is for the same reasons that you listed it as "difficult to integrate into assembly". This is one of the big reasons why steel is great. It doesn't matter how much it cracks, buckles, bends or shears, you can just hammer it straight with a bit of heat, grind out any cracks and fill them up with the welder and even heat treat the part again if it's critical. If your fancy composite part breaks, it's trash, and unlike metals it's not just easily melted down and made in to new metal. I like repairing things and I get very displeased when I cant just fix something that breaks. Another disadvantage with composites is the brittle failure modes with almost no warning signs. If I have a chain made out of steel, it doesn't just snap off abruptly, it will stretch first, at first elastically and then plasticly. If I don't overload it too much, I can see that my chain is being pushed past it's limits and I could take measures to avoid catastrophe. With composites it's not like that, it either looks totally fine, or it totally sheered off. Though I guess it's has it's applications for euthanizing billionaires wanting to dive to the Titanic.
Excellent presentation. I really like the way you develop story around technical topics. I have expertise in Fibre Reinforced Polymer materials used in Structural Engineering applications.
Great video on composites and OnShape features. Could you do an introduction video on how to calculate Carbon Composite Structures Strenght and Modulus using OnShape. Take for instance designing in OnShape a simple container/monocoque using a Sandwich Composite with a Foam core material, and how to use OnShape to calculate its resulting Strength (MPa) and Modulus (GPa) in different directions. That would be cool, and its applicable to allot of structures from Polymer, Ceramic to Metals.
i love the video , it summarize a lot. And I love the animation. If you please tell me how you did it :D or what software or app did you use ? I need to make a presentation as cool as this for my dissertation ^_^
Wow you're just in time, I've just had a course on composite materials and your video will help me go deeper and understand the concept better. Keep up the good work
Carbon fiber is a miracle material. My road bike frame barely weights 2lb, yet handles my 190lb body on the bumpiest roads without budging in anyway. The top tube has sections that are as thin as a coke can, but feeling it you'd think it's solid all the way through.
I'm pretty dumb. Barely passed high school, but this video actually made me understand wtf a composite material is in the simplest of terms and built it up to more complex understanding. Great video. Oh an also ... They definitely figured this shit out from the crashed UFOs. 10000%.
