World’s toughest material created by tying slip knots into weak, commercial thread

[QUOTE]Nicola Pugno, at the University of Trento in Italy, has succeeded in making by far the toughest material in the world — by taking a conventional piece of fiber… and tying it in a slip knot. This method seems (and is) so simple that the inventor is calling it the Egg of Columbus, which refers to a discovery that has eluded mankind forever — but seems incredibly obvious and easy after the fact.[/QUOTE]
[QUOTE]I implore you to put the question of commercial viability aside for just a moment, though, and bear this in mind: Pugno theorizes that knotted graphene thread could obtain a toughness of 100,000 joules per gram — about 1,250 times tougher than Kevlar. Imagine the bullet-proof vests you could fashion![/QUOTE]

Cool. Now figure out how to tie the literally millions of knots per gram of the material for this to work.
It may even be possible to use science to tie those knots - think of how a magnet works... one force repelling / attracting another. It's not likely to be simple (or perhaps possible of course), but maybe if exposed to the right environment graphene may be able to be manipulated into forming complex strands, and if those strands become large enough then knotting may become far simpler etc etc.
Fucked if I know, I'm just a hick.

saw this and got really excited for a thread about a really tough man
why did you get really excited for a thread about a really tough man

Does this mean we don't have to stuff ceramic kitchenware in our ballistic vests anymore?
How would you even have rocket proof clothing? The rocket might not penetrate the clothing but that's not really that important with rockets due to the whole explosion thing.
It's like saying you have mine proof shorts, they won't stop the mine taking your legs off.

no they wouldn't. the kinetic force would pulverize anyone wearing it unless you were wearing shock absorbers the size of gdansk and even then you'd still be bruised.

its like they think bullets are magical hitscan laser beams that just cause injury

even if you wear heavy kevlar nowadays, a shotgun blast or high-powered round to the chest will still bruise the fuck out of your ribs.
The best thing about graphene is, you can easily make it at home:

Cool, now do it with carbon nano-tubes. Everything is more awesome with carbon nano-tubes.

Such a badass picture.
NO MISTAKE HERE JUST UH NOTHING
Science has confirmed that metal is the strongest material in the world. Called it.

Before we had ballistics gel molds, we had men who could take such pathetic mortal weapons :v:

If I recall, a rifle will snap ribs even through one of those military ceramic plates on the chest (which is the most armoured part). That's the problem with exoskeletons too.
Squash head rounds are a good example of this. The shockwave travelling through the outside armour of the tank is enough to detach a part of the interior one and shred the crew (in the case of a bodyarmour, that shockwave goes straight into your ribs/organs).

If you were wearing an absolutely unbreakable vest with cloth-like thickness and flexibility and got shot you'd still get fucked up pretty bad
The ceramic absorbs the hit so your squishy organs don't have to
[QUOTE=W00tbeer1;40477604]Such a badass picture.[/QUOTE]
How many people have such faith in their inventions these days to do something like that? I mean apart from that crazy guy who hides behind his bullet proof glass while he invites people to shoot at it with an AK.

this is why we need to make all our military units wear two-inch-thick rubber suits and then ginormously thick babygros

sadly some people dont realize that bullets don't impart much kinetic force and cause much more damage with fragmentation and penetration

Wouldn't call graphene "conventional" - but is easily made.

That's the point at which you add exoskeletal joints with powered servos.
