Glued Poop. Cuz its shows how meaningless Composite Materials means.

[@Colonies_Dev]

just not for experimental titan submarines lmao 🤣🤣

[@Colonies_Dev]

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

[@NaimurR]

This video summarizes the three-credit Composite Material course I took in my senior year. Extremely high-quality content. ❤

[@SirSpence99]

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 !

Appreciate it Fabien, thank you! :)

I cannot believe such high quality videos are available for us for free... I can't thank you enough for what you do for us.

[@H.K.MahediAzad]

As a prospective researcher in the field of Composite Materials, I must say that this is by far the best content I have seen on KZbin.

[@asdzt123]

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.

[@abowden5079]

[@georgedreisch2662]

😂😂😂 …or NASA begin using plywood as a ablative for re-entry vehicles, as being equally appropriate to application.

[@Tensho_C]

​@@georgedreisch2662 i think nasa has legitamite reasoning here, compared to oceangate

[@ReaperThugX]

Too soon 😂

[@ccarlock8537]

​@@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

[@turbo_brian]

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.

[@Toxic__rl]

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

[@Praddy07]

Always so informative. I’ve learnt more from you than i have in my Bachelors degree. You should be a staple for education.

[@ДмитрийГончаренко-с2ш]

As the composite materials engineer from university, I have to say - this video is incredibly informative and accurate! Definitely would recommend it to students

[@Pauldyke]

Fun fact: Reinforced Concrete is the most commonly used composite material.

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 ..

[@TheRevanchrist]

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.

[@varunahlawat9013]

insanely precious of a video ❤

[@user-nu8in3ey8c]

This is the best video on composite materials I have ever seen on KZbin. 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.

[@hamdinet17]

Video link please

[@manis404]

I now get it. These presentations are what cause automotive engineers to go: "I should use plastic for that intake manifold"

[@Turbokilpuri]

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.

[@MichaelSkinner-e9j]

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.

[@stonehead4775]

[@nicolashuffman4312]

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.

[@RedgeIsLearning]

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

[@skitidet4302]

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.

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..

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
