Carbon fiber is several times the strength of steel per mass, but it is also very brittle. When its breaking force is reached it fails abruptly. You need to laminate it with a strong, flexible material like Kevlar, Dyneema, or Spectra, and you need a minimum of 10 layers (probably more) if you intend to stop arrows from a war bow. Also, the epoxy must be vacuum chambered and cured in a kiln or oven to remove air bubbles and catalyze the resin to maximum strength. The resin manufacturer can tell you the optimum temperature to cure at but if memory serves it is somewhere in the neighborhood of 80 to 90 deg. C (aerospace standards) to achieve maximum strength.

[@davidbeppler3032]

Yep, it would be an inch thick if it was the same weight as steel. Doubt an arrow will penetrate an inch of carbon fiber.

[@hf117j]

To be a solid backbone and prevent the deflection surface from deforming or caving into a dent that can lead to penetration. The resin could catch the tip of an arrow and stop it from deflecting. But a pure surface has a better chance of letting it slide off

When I was younger, I was on my high school rowing team and one day we got a criminal, fiber shell, and you are indeed correct it’s a miraculous material but it’s very brittle It is very vulnerable to crush forces.

The durability seemed fairly good for such thin sheets. You could easily make armor multiple sheets thick and still be lighter or thinner than regular armor. Something multiple sheets thick would probably be quite good.

[@Dead_Pool_Rising]

I'm not convinced of that at all. Not from what I just saw. I'd have to see a properly shaped piece of armour made from carbon fiber get shot to make that kind of claim. I've seen what mild steel can do to stop arrows when properly shaped and treated. I.e. it can stop a 160 lbs longbow and take almost no damage. That carbon fiber struggled with 110 lbs and the arrow still got through. The problem with carbon fiber is that the moment it takes damage, it becomes so much weaker for the next blow.

@@himedo1512 Carbon fiber is about 1/3 to 1/4 the density of steel. It makes a good amount of difference, but it's not exactly a super futuristic ultramaterial. 4mm thick carbon fiber plate armor would be awesome, be able to stop 12th century cannons, and be the same weight as plate armor of the day, but having armor that's that thick would cause problems around points of articulation. Not to mention that the knight would be very unlikely to survive the cannon, regardless of blunt penetration. The biggest issue with carbon fiber is how inflexible and fragile it is when you're using resin. Against a war pick, hardened steel would likely perform as well as or even better than carbon fiber that has been properly meshed and hardened simply because most steels deform so well and are less likely to shatter into multiple pieces. In alot of ways, it's similar in effectiveness to ceramic armor. Super effective against a single shot, but after that, it rapidly becomes extremely useless.

Would a small brick of plated iron not provide some information?

[@Dead_Pool_Rising]

​​@@HvacHeathenNot really. I've seen what a properly shaped iron breast plate can take, and it's a hell of a lot more than a small brick can. I don't even know if shaping carbon fiber in the same way would yield comparable results until I see it done tbh. A big part of me doubts it because carbon fiber just isn't like other materials. The strength comes from the weave and not necessarily the shape of the object it's made into.

[@michasokoowski6651]

@@Dead_Pool_Rising Another thing is that different materials have different resistances to different types of trauma. Steel is amazingly good when it comes to taking pressure, which makes it an amazing material when it comes to armour. Carbon fiber isn't, it shines when it comes to resistance against expanding. That's why it's amazing material for space projects and was a terrible material for a submarine. So it would be hard to shape carbon fiber in such a way that it would truly shine when it comes to resistance to external forces.

[@Destroyer_V0]

Carbon fibre on it's own is not an effective armour. It's light and rigid, not tough. Carbon fibre sandwiching a layer of kevlar, repeated 16 times however. Now you are getting some fairly cut resistant armour at least.

[@davidbeppler3032]

Make the Carbon Fiber an inch thick and show me an arrow going through it. ;)

[@silverjohn6037]

If you're comparing modern materials maybe check for polycarbonate sheets like Lexan. These are used for replacing windows in areas at risk of vandalism as, while they may scratch, they're resistant to breaking and, too a limited extent, small arms. Quarter inch thick is standard but it would be easy enough to cut a sheet and bolt several layers together. It might actually work better than carbon fiber for armor or shields as it's softer and less likely to shatter.

[@Sukenus]

I believe you need a much thicker layer of lexan to withstand the same amount of punishment as carbon fiber, so it's definitely less efficient, but I guess it would be more cost-effective. I have worked with lexan and steel sheets before and from my experience, a 1.5 mm thick lexan was easier to cut than a 0.5 mm thick mild steel and a 8 mm thick lexan was easier to saw through than a 1 mm thick mild steel (with the appropriate saws). But I have obviously not tried arrows or bullets (or carbon fiber). Speaking of bullets, Scott from Kentucky Ballistics easily blasted through a half inch thick "bulletproof" lexan with a standard 9 mm pistol. So you gotta get extra thick with those to start stopping some bullets.

[@MissionSilo]

Then composite for all purpose armor?

[@garethbaus5471]

Honestly HDPE would probably be even more interesting in this application.

[@voidseeker4394]

​@@Sukenus polycarbonate is NOT hard. It's not resistant to scratching, sawing, miling, and similar types of damage. What i noticed tho, is that it doesn't crack or shatter from blunt force, it bends like metal instead, to an extent. I had lexan industrial-grade protective googles that wore of and weren't usable anymore, so i shot them with a pellet gun. They stopped the pellet, but it left a dent similar to ones that are left in sheet metal, sleek round shaped, with no signs of cracking that you'd expect from plastic. I think the googles were like 1.5mm thick polycarbonate.

[@hf117j]

​@@Sukenus Polycarbonate itself isn't bulletproof and anyone that believes it is, is an idiot. It is however, one of two materials used in bullet resistant glass. Glass fragments the bullet. Polycarbonate absorbs the fragments. It is worth mentioning that transparent aluminum does a much better job, being capable of stopping .50 bmg in the same thickness as the typical layering for ballistic glass is made for stopping normal rifle rounds.

CF is a great ingredient for composite armor. Important part is composite. There's a new technique to make graphene. It's really cheap, but a lot of time consuming lab manual labor. For a one-off suit of armor it would probably be worth it, I would throw some of that in the resin. I would also add a few layers of Kevlar so it's useful in a modern context as well. I would also continue to use metal plates but make them half the thickness and back them with the composites. So you end up with the same weight but double the protection or same protection and half the weight.

I'm imagining putting this over textile armor would be a really good combo. Giving it something to diffuse the force into. Probably still wouldn't be as durable as plate, but might be pretty darn good, especially vs any kind of cutting slashing action. Seems like its only really weak against piercing stuff, but if it stops it enough that it wouldn't get through the textile underneath, might nonetheless still be really effective.

[@hf117j]

It could be highly effective spaces armour. Bind an outer carapace with one about half an inch under by the edges. Run bolts and nuts through as support pillars, the ends can be smooth on the outer shell if desired. Otherwise it may wear your opponent more to have their strikes unpredictably stopped in jarring fashion. Of course under that, still the other stuff

[@RauschenPauli]

the arrow test suprised me. considering it was a very thin piece and flat + the arrow did get stuck pretty early.

[@r3dp9]

It seems it pierced fairly easily, but got rapidly slowed down. I think the fibers got pushed apart, which meant they tried to squish back together, causing friction on the arrow. Steel and the like are more likely to bend out of the way.

@@MrRourk It will be worse. Broadheads are made to slice through unarmored flesh of game animals or burglars. The field point on the first shot was the best tip they could have used of the ones they had. A bodkin would have been superior to all others. The second head they used was a semi-broadhead and the fiber stopped it almost outright. The one you listed, while beautiful and functional, would fare worse. The fiber would catch the blades and just outright stop it. This is what gambesons are for; the weave catches wider arrow blades and can even hamper bodkins.

[@robertbacklund4438]

I am a retired aircraft technician and have a lot of experience with advanced composites. Carbon fiber is very strong but it is not very resistant to cutting or being pierced. Kevlar is far more resistant to being cut and pierced. All of the modern body armor uses a lot of kevlar. Most bullet resistant vests for higher caliber bullets also use ceramic and steel plates. I think for resistance to swords and arrows several layers of kevlar with a backing of carbon fiber would work well. Also if you have access to plate armor you should use it as a form. Put on several coats of mold release wax then do a wet layup starting with 3 or 4 layers of carbon fiber (the first sheet should have the weave being at zero degrees in relation to top and bottom of the breast plate with the 2nd layer being oriented at 45 degrees with the 3rd layer 45 degrees opposite to the 2nd layer with the 4th layer at 90 degrees. Then follow up with several layers of kevlar with the same orientations as the previous ones. Then put this into a vacuum bag with a vacuum pump while the resin cures. Look up how to vacuum bag a composite layup. Before putting it in the vacuum bag you put a sheet of perforated plastic sheet, then a sheet of breather cloth. The perforated sheet is usually mylar that has a series of small holes on a 3/8th inch pattern and the breather cloth is very similar to polyester fiber fill sheets used in making quilts. This is readily available at fabric stores, the thicker the better. The perforated sheet prevents the breather sheet from sticking to the layup. The holes in the perforated allows the excess resin to be sucked out, the breather sheet serves two purposes. It absorpts the excess resin as well as giving the vacuum bag to evenly apply the force of the bag across the whole part. When you suck the air out the air that surrounds the part presses down with 14.6 lbs per square inch. Using a vacuum bag gives an optimized ratio of resin to cloth which gives the most strength. A resin rich lay up is far weaker and very brittle. You will find that a composite breast plate with its compound curves will be very strong and should resist sword blows as well as arrows. If arrows pierce it make one with more layers of kevlar.

[@sonofagun1037]

I work in composites as my day job and I can tell you there is not really much of a point of using foam core in a carbon fiber sword. The sword is going to be thin enough as it is that you won't need many layers of carbon fiber to make a traditionaly thick sword. I would just make sure you have at least one layer of UD in the center of the sword to give it rigidity. Biaxe UD Biaxe would probably do the trick. For weight balance I would just put something more dense than carbon fiber in the hilt. Definetly do a vaccum bag after you layup. Infustion would be prefered but thats more complex, you can just wet layup and throw it in a vacum bag and apply like a bar and a half of pressure to it and there yah go.

[@hf117j]

Skeletonized steel core was my thought. For balance you could do a bit of tungsten or something in the hilt. Depending on the total weight, of course. I think the steel cire is important to holding an edge against other weapons. Skeletonized for weight, and would probably have benefits in structure. Then the carbon fiber maybe inset on the sides if possible to add the remaining rigidity. I think this would work especially well in the blade of Ichigo from Bleach. The curved design would allow for plenty of deflection and glide. To me that means even if you manage to be overwhelmed with a giant sword, it should be light enough and tough enough to not let you down. Hopefully resulting in a genuinely useful partner if for some reason you have to use a sword

I've been steering towards boring lecture and fabrication type stuff and more towards exotic materials but this was popular, released recently, a channel I've spent dozens of hours on, and very very topical. This should have ABSOLUTELY been recommended to me. It's also a great alternative to all the powerpoint presentations.

[@ulfhedtyrsson]

The arrow was very impressive. A mil of steel and Boromir would have been absolutely skewered. Considering the width and weight I think it did great. I think a mil of sheet steel on the outer layer would go a long way to stopping the edges and a thicker middle layer of foam would go a long way to stopping and absorbing a lot more kinetic force to slow down the chops and cuts before they transfer all that force through the entire piece on a very thin point or edge. And it wouldn't add much ofma difference in weight.

[@javaesme4692]

Carbon Fiber doesn't respond well to direct impact and penetration - the material is simply too brittle by nature. My advice is trying out the 'CFRP-Stainless Steel Superbeam' concept, which is fairly new in construction and architecture. The way it works is by 'Jacketing' each material in order to increase the structural integrity. It's basically a carbon-fiber core coated in resin, encased in steel. If you intend on making the Titan Sword, it should at least cut down on the frame's weight while offering up to 95% more load strength. That means you can use almost half the intended weight to support the frame, and still get the same sword.

[@I-didnt-ask-you]

One problem I want to bring to attention is that non of these pieces look shaped like armor would be to redirect and deflect the energy of blows, for example arrows or axe blows would have a harder time connecting a perpendicular hit and glance off on shaped armor. If using flatter pieces, having stacks laced together more akin to traditional Samurai armor would have been a better test if wanting to use simple flat pieces.

[@j4ff4c3ks1]

I'm no material scientist of any kind but would fiber based materials be weaker against piercing forces like stabs and arrows than solid materials due to the fibers separating?

[@WilliamLee-bv4tv]

Hey Shad, love your channel and especially how you're turning it into a business. Keep on your path!

[@alexandresartori2000]

Good video, although you should try a heavy vacuum pressed 50 layer carbon fiber 1cm thick plate... Expensive? Yes, but it is used on the Beechcraft premier belly, so it can take some hits and some serious punishment...

[@thecarbonfibernation]

While carbon fiber on it's own is very strong, it does not have a particularly high abrasion resistance. When making anti penetration panels like those found on race cars for nearly this exact same reason, you normally rely on Aramid fibers such as Kevlar or Zylon. If you add a core structure in order to add stiffness while keeping weight down you are practically relying on the strength of the foam rather than the strength of the fibers and resin. The bonds in the structure of the foam will fail before the Carbon, and then it will buckle as there is no structure supporting it anymore and you will see it separate like the example you showed. It was not de-laminated, the core failed. Cheers, Love the videos.

[@drewwilliams7794]

[@Kristina.Larson]

When carbon fiber is under tension, it holds up well. Under compression it tends to delaminate and crush. The edged weapons pierced pretty well, and the axe and katana would snap the resin, causing the whole plate to collapse. One important point about these, same as Kevlar for vests, is that they take damage from each hit and do become more likely to fail with every hit. If an officer takes fire and their vest is hit, that vest is expended and needs to be replaced.

[@calpalius8943]

get some rest Shad, we love you guys

[@jegsdinogod5091]

This is the sword tuber equivilent of the gun tuber armor plate debate. Ceramics? Or steel plates?. Unfortunately carbon fiber isnt great at shock absorbtion. Ceramic plates (of which there are several types including those not actually ceramic) have a limit until they crack ir shatter in which case theyre useless. While steel can be hit numerous times....but is a shit load heavier.

[@HichigoShirosaki1]

Considering those carbon fiber pieces are practically as thin as paper and unfinished, the fact they could stand up at all to any hit is amazing.

[@svendragon8139]

The loose fit actually helps the carbon fiber here as the force is allowed to tilt the piece inward and increase the final angle at which the force of the edges are at their greatest.

[@123FireSnake]

god one of these days Boromir is gonna grow a pair of legs and walk off that fungus invested thing is getting nasty :D

[@Karma8Kami]

The delamination issue could probably be solved cheaply by drilling a few holes and putting pop rivets in strategic places. One could also vastly increase it's armor value without increasing the weight to much by using cheap metal strapping with holes to run a mesh across the armor, makes it much stronger vs bladed weapons but doesn't do much for arrows, the attachment points then serves the same purpose as the pop rivets.

[@longrider42]

From what I've always understood. Carbon Fiber will only stop blunt force trauma, Like a bullet, but even then an armor piercing bullet will go right through. This is a very entertaining channel.

[@HazzaTheFox]

It's a bit worrying that the swords bite into the edge of the fibers so easily, as those are the dimensions you'd really want to keep their shape if they were swung against something else (though I guess they're omitting the hard steel edges and possible springy materials to cushion the blow). I love how the different parts of the axe were used against the actually-tough carbon fibres so we got an idea of how well they actually work (especially after hearing so many people swear axes/picks weren't "really" used against it.)

[@angryginger791]

You guys should try some injection molded carbon composites. I did a facility tour at a supplier for work a while back and they had some ridiculously strong and light stuff. It's not as pretty as carbon fiber weave, but it's strength is omni-directional. It would also make more sense to use for kitting-out an army. The mold is expensive, but once you have it you can produce pieces very quickly and cheaply compared to layering weave. You'd need several molds to account for various sizes, but even then, if you are armoring thousands of people, economy of scale would more than make up for the upfront cost.

[@RMX7777]

I believe fiberglass would make a better armor. One of the main properties of carbon fiber is its stiffness, but in armor you need to dissipitate force. Making the armor from fiberglass would allow it to flex when hit and then return to its original shape, which should allow it to perform better. I imagine an ideal armor would be fiberglass with a thin sheet of stainless steel or titanium over the surface.

[@hf117j]

That's good for most things. Bad for piercing. If something can make a dent and still has energy left it will pierce. Plus fiber glass has safety issues aside from that, meaning if your armour is damaged and you live, your wound will itch, your respiratory system will be affected. It's a whole thing. Polycarbonate though is excellent for impact resistance with none of those issues.

[@RMX7777]

@@hf117j While true, fiberglass is also very strong. This means properly shaped fiberglass armor will deflect piercing blows before they cause the material to flex. It's only when the blade bites in that all of the energy will be transferred in and potentially pierce the armor. This is one of the reasons I suggested plating a thin layer of a high hardness metal over the surface, as this will help prevent weapon tips from biting in. As for the itchy wounds, the resin will hold the fibers in place, so it's not likely to be an issue. Regardless, I'd rather have an itchy wound than a pole arm through my chest.

[@SkunkworksProps]

It's funny that you've done this, we were just down at the archery range firing arrows at carbon fibre and fibreglass pieces to see how they'd do (spoilers, not well). Got another more extensive test planned with different layers, cloth weights, as well as some kevlar parts.

[@bigd4366]

I have no idea how expensive it would be, but I'd love to see some testing of laser-sintered printed steel armor--say, with a hexagonal structure to allow it to be thicker and more resistant for the same or less weight. Also, shouldn't these sample tests be secured against a gambeson backing?
