Microbullet hits confirm graphene's strength at Rice University

Graphene's great strength appears to be determined by how well it stretches before it breaks, according to Rice University scientists who tested the material's properties by peppering it with microbullets.
The two-dimensional carbon honeycomb discovered a decade ago is thought to be much stronger than steel. But the Rice lab of materials scientist Edwin "Ned" Thomas didn't need even close to a pound of graphene to prove the material is on average 10 times better than steel at dissipating kinetic energy.

+CK A Because of mass manufacturing of graphene sucks!! How many years did it take for silicon chips to develop?? Ever thought of that?? Aren't you a college graduate?

[@macrocosmcat6920]

Sadly Graphene is brittle. In theory it looks good, but mostly graphene only works as a powder and here is the biggest issue. It doesn't get along with other material, which means, yes, it can't be combined with other to harden the composition. So it's never gonna leave the lab.

[@williamball7511]

The problem with graphene is that it's a 2D structure! It does not scale! 3D graphene is graphite, and that's weak because very little is holding the graphene sheets together, save for weak Van Der Walls forces.

[@blackjoker2345]

Actually, the main issue with graphene is making continuous sheets of it. The reason graphite is weak isn't because it's make of sheets stacked on top of each other, it's weak because its made of tiny sheets no larger than a grain of sand wide and full of elemental impurities that break up the structural integrity. If you were to make continuous sheets of atom thick graphene with the length and width of a credit card, you could stack thousands of those sheets on top of evach other as much as you want without losing structural integrity. Unfortunately, we're still struggling at making continuous sheets of graphene without other elements getting mixed in and weakening the end product.

it looks so smooth omg

[@ira1420]

Basically you could build a 60 mm plate of graphene with the same amount of protection against kinetic energy of 600 mm of armor and with the same weight of a 6mm steel plate

[@MrWhangdoodles]

It'd break the heck out of your ribs. It'd replace kevlar but not solid plates. You'd still need something like steel or ceramic to absorb the energy or you might not be full of holes but you'd die of internal bleeding from ruptured tissue and blood vessels from the massive punch in the gut

[@ira1420]

@@MrWhangdoodles yeah obviously it gotta be composite, but even as composite, the shock would be to big to be absorbed by your body. But the situation would change if you used graphene in a tank: you'd just need a sandwich of 15mm of steel + 100mm of graphene +15mm of steel +some anti spawling material to have a protection equivalent to 1030mm of steel at the weight of a 45mm plate.

What i want to ask is if employed on say a satellite how are you able to come up with a thickness or model of what you would need for protection from micro meteorites, is there a velocity or uniform speed that you use or is it based on theory. I would also like to know what happens to graphene when you have a lot of it together does it act the same or does it become reliant on its shape or form.

[@pranav_indoria]

I do understand that preparation of graphene for conduction of heat and electricity is rather easy. Just use those thin sticky sheets with graphite dust... My question is how do I obtain/prepare the strong version of it, like the one that can be used for strength demonstrations?

so this in combination with spider silk amor could basically be a really good sub dermal set of body armour. couple that with traditional armour reinforced (or outright made of graphene as well.) and you'd have really friggin good armour. not to mention sub dermal armour is virtually undetectable, unless under X-rays.

what does a bullet 3 microns thick at 1km/sec do to your hand if shot at it? would you feel anything? will it go through your hand? will you bleed?

[@UncoverMysteries]

Wait Graphene is only 10X better than steel now? That used to be a much bigger number. What happened? And it's also per weight and since carbon is much less dense, it would take more volume of graphene to = the same penetration proofness as steel. What happened to the whole, you can stand an elephant on a single layer sheet of graphene analogy? I'm sure an elephant can't stand on the equivalent sheet of steel without it tearing.

[@ChrisPrefect]

3:00 why do you show the graphene film with individual atom bond strings but the micro projectile is a solid ball?
