Carbon Fiber - The Material Of The Future?

[@RealEngineering]

BA BA BA BREAAKING NEWS....YEAH. First phase is complete. Website is live at www.realengineering.net. Next phase will be launching a site where we will be working on companion articles for each video we release. This site will not be monetised with ads, instead it will hopefully be supported by people like you who enjoy it by supporting us over at www.patreon.com/realengineering

Please do your next video on Graphene.

[@alephii]

Frank Dantuono but isnt graphene more a scientific curiosity rather than a usefull engineering material?

[@RedTriangle53]

it's a scientific curiosity because it could revolutionize every single field of engineering

[@alephii]

RedTriangle53 like carbon nanotubes that has been around for +30 years and with no engineering applications?

[@RedTriangle53]

Like carbon nanotubes on steroids that are mass producible. Carbon nanotubes have been difficult to work with because you need to grow them under high pressure as crystals. Graphene can be made with the laser drive on your computer. It is also a fact that nanotubes have an incredible amount of engineering applications. Lack of industrialization does not mean lack of potential. Carbon nanotubes are also not useful in electronics. Graphene is immensely so, for both commercial and scientific applications, which makes it much more affordable even if it wasn't easily mass producible. So actually no, not like carbon nanotubes.

[@michalvalta5231]

Didn't you watch the video? People thought there is no useful engineering application for carbon fibre for decades... You are gonna say the same about graphene now? Like, seriously? You are not joking? ... Humans never learn... Still the same silly mistakes. :D

I love how you say “Carbon” it’s beautiful “caair Ben”

[@kylehunter8800]

For a while I helped an engineer at my previous job who was trying to develop bushings and bearings from carbon fiber. We would use carbon fiber sleeves and pour this slurry through the sleeve as it ran through these rollers. Then we would wrap it onto a cylinder and it would go through a series of heat treatment and put in a vacuum chamber submerged in a polymer. I remember delamination was a constant issue along the face of the cylinders and we tried to resolve this by compression in a mould, different hand wrapping methods and even cross layering it as talked about at 6:25 I left the company and still wonder if they resolved the issue. Very itchy stuff, would recommend a respirator gloves and long sleeves.

[@timothymclean]

Of _course_ it was sports that got laymen to care about carbon fibers. Science, engineering, even space? Meh. But someone hit a little ball really well thanks to carbon fibers? Wow, they must be important!

[@21BDP21]

Timothy McLean People are also willing to pay more for sports equipment. Why would the average person care about the increased tensile strength or the other properties they don't understand. The average person can feel and see the difference with something they can hold vs a giant black tank.

[@RealEngineering]

Commercialisation is a huge first step to making the material affordable for everyday applications.

[@failandia]

thus we have to play golf on the moon ! wait, already done ^^'

[@timothymclean]

21BDP21 I'm not convinced that the average layman would notice the difference. Professional athletes, sure, but laymen are going to be limited by their own skill and similar factors more than their equipment. I'd expect "We can send more stuff to the moon" or "We can spend less money on jet fuel" to be about as grokkable as "We can hit small balls slightly farther".

[@DrewLSsix]

[@WookieChewie13]

Dear OceanGate

[@enderman6777]

This is a great channel, because you, sir, understand what you are saying, like it, want people to understand and give lots of useful info. Unlike most other channels.

[@Spymask-AoC]

I have a question: is the heat resistance of the fibers themselves enough to withstand molten aluminium ? Could it be possible to create composite metals ? It would be interesting to see how metals crystallizes in the presence of aligned fibers. Maybe that can help reduce micro tears ?

[@dragonthefirelord]

There have been tests done with creating carbon fiber-metal matrices. In many cases, the composite has superior properties when compared to when the materials are on their own, but the properties are still dependent on the geometry of the carbon fibers. A better solution, at least from what has been observed, might be to utilize CNTs in metal composites. You could disperse multiple strands of CNTs in different directions without significantly increasing the bulk of the metal composite. Carbon fiber might be better suited being used as a reinforcement for structural concrete in place of conventional reinforcements, as tests have shown that it does improve the properties of concrete.

[@Spymask-AoC]

Those results with concrete where why I was wondering if it could be used to reinforce other materials. And it makes sense that an already strong structure could be better suited to reinforce metals, but I was just wondering about the possibilities of carbon fiber, because, ya know, they are easier to manufacture. If I had the capacity to do it, I would be making all kind of combinations with the fibers. Other that also makes sense in my mind are ceramic materials, but again, they would be better materials with cnts, but, what about affordability ? Carbon fiber reinforced ceramic conductor caps, for example.

[@dragonthefirelord]

The problem with trying to utilize carbon fiber in ceramics is that ceramics are typically used in applications where the operating temperature exceeds that at which carbon fiber remains functional. Contrary to what intuition would say, in silicate-based ceramics, carbon fiber actually increases embrittlement in the composite do to it reacting with some of the other materials present in the ceramic and creating porosity within the matrix. In order for carbon fiber to be utilized in a ceramic matrix, it would have to be in lower temperature applications than what would normally be done for the ceramic. One such application that is promising is the use in ceramic saw blades. The increased strength in the blade would mean that the blade degrading due to stress would be mitigated and the fibers could prevent micro fractures from propagating throughout the structure. It is something that wold be extremely useful if the above mentioned issues can be adequately solved.

[@olekaarvaag9405]

Fantastic video! When you mentioned the many questions you still have, and the lack of good questions in the SpaceX Q&A, I imagined how great it would be if you were to be an integrated part of the Q&A. Not necessarily exclusively, but it would be amazing if you somehow got teamed up with SpaceX to ask questions in the Q&As that most of us never even think about. It would help educate a a lot of people, and make us understand why certain things are as important as they are.

We use the woven fabric for the bulk of our solar car's shell. Specifically the first woven fabric of the two that were held. We use several layers over the mold to make a stiff solid structure, intertwining hex comb layers for stiffness.

Specifically I'm from SIUe, but as more schools are able to learn and get funding, the American Solar Car Challenge grows.

He developed carbon fibre filaments that lasted longer than other filaments. The better products get the sale. That's the nature of business.

[@orestasvanagas9572]

there is gain... it's called colonization of the universe.

[@PistonAvatarGuy]

We should send humans to Mars, sure, but the resources required to start a colony there would be absolutely staggering, and no country on Earth has such an excess of funds and resources that they could start a colony on Mars without seriously damaging their economy. Combating climate change should be the top priority of every human being on Earth right now, this is just another distraction from actual problems that human beings currently face. It's very likely that we'll never be able to leave our solar system.

[@cmiller1515]

idontcare80 I would not underestimate the human race's rate of progress. Quite frankly, I believe that colonizing mars will speed up the process of escaping our solar system. Sure, it may be impossible to travel outside our solar system now, let alone colonize mars, but in the long run we will gather much information when going to mars, that will ensure our success in leaving our solar system.

It's the most practical choice. Nearby, has most of what we need to sustain humans there, and if we get really silly, if we were able to put enough shit into it's atmosphere, it would stick around for long enough timescales that we wouldn't need to worry about it's depletion.

vide0viwer you're scared of progress

[@jamesburleson1916]

Would you rather go to Venus where the surface pressure is 92 bar? Humans are hard wired to explore and expand and unless we annihilate ourselves in some stupid display of political chest thumping we will, as a species, spread to other planets and solar systems. The only question is if you and I will see it in our lifetimes. I, for one, am hoping that one day I will be able to live on another planet, but I suppose we shall see.

[@seigeengine]

James Burleson Other solar systems are looking pretty unlikely, actually, but expanding to multiple planets is pretty important. Now if only we could get Venus to donate some of it's atmosphere to Mars. Other than Mars, there are some promising moons, the idea of a floating city on venus is iffy, and then there's spacestations.

[@vide0viwer]

+seigeengine Mars has around 1/3 gravity compared to Earth: With a species that has developed under Earth's gravity will mean drastic changes will occur such as bone and muscle loss, this is not including unknown long term mental and physical symptoms that may occur. Also because of the gravity women may not be able to conceive children. -Extremely cold temperatures even for summer: This means steels and other materials will be a lot more brittle so only specially designed materials will only be practical which means $$$. -No magnetic field means you will be facing solar radiation on a daily bases so its either live underground or build thick walls. -33 million miles from Earth: any emergency supply requests will take months to arrives and if a colony fails after spending billion will just make humanity more closed minded to space colonization. I will be more convinced of a colony on Mars when we are able to make a self sustained colony on Antarctica which is 10x more habitable than the red planet. Also if we want to colonize space the Moon would be a better candidate. +96mtbrider see answer above.
