Some stuffs I've seen on Internet, I don't know how much of it is true, but apparently there is a theorical form of carbon with atensile strength of 10 BILLIONS GIGAPASCALS!! !! !! !
In perspective most steels don't reach 1 GPa and the theorical limit of carbon nanotubes is 160 GPa. It would be made of carbon benzen like rings looped in each other, like a chain mail.

I wonder what it would look like. :?:

This does indeed sound very cool. Thanks for sharing.

Wonder how this would change war.... navy seals with practically invincible armor.. imagine that!

A little mention from Nature no less.

The good news, if the wrong people got their hands on that technology, you could still liquify someone within that suite pretty easily.

it won't stop Newton's laws of motion…

getting hit by a projectile would still transfer a huge amount of kinetic energy that has to go somewhere… and that alone could potentially kill you… even though the carbon ring armor has not suffered any damage...

:wink:

Well bullet proof armor is pretty thick and I have heard hurts a lot and leaves a bruise. I have no idea how it would feel to be shot while wearing a .1 mm thick bulletproof carbon nanotube chainmail. Maybe someone with more knowledge of materials science could hazard a guess.

I think this could be ideal for a few other things though: bridge construction, umbilical elevators if we ever decided to have elevators to space for construction, reinforcing all kinds of parts used for industrial applications, that and a mesh of this in your tires could provide a very long life.

The phrase "made out of whole cloth" will take on a new meaning.

The vest won't have any significant weight to bleed energy from the bullet so you are still going to get hit with anywhere from a couple hundred to a couple thousand foot-pounds in a small area and may also press the vest into the body cavity a little. If the vest was one solid mass it would spread the force out more but would just cause widespread injuries to the torso and lower abdomen similar to sudden deceleration trauma. There are ways to lessen these effects of getting hit, but they are a long way from designing those components into a vest.

Depending on how tight or loose the weave is is what will determine its stomping potential. If you hand a blanket on a line and don't way the bottom down, it can stop bullets. When the bullet impacts the rings it energy can be dispersed through the surrounding ring outward. Much like ripples in a pond. The problem with a solid plate is the sheer weight and lose of mobility. This could be able to be a mix if woven right soft enough to catch the bullet so as not to damage the armor yet strong enough to keep its shape so whoever is wearing it is not harmed. A layering effect could also be used to help.
