	Carbon Nanotubes to knit bullet proof armour

carbon, nanotube, bulletproof, kevlar, flexibility.

pokkets says:

The Nanotubes can transfer more energy back to the bullet after they absorb and spread the impact, because of their greater flexibility. Polymers like kevlar can spread the load, but can still result in internal damage.

how hard is it to manufacture these things? when will these be mass produced?

Labs in the U.S. and some european countries have been working on the same for the last 10 years. As for everything, I guess it's just a matter of time before it is mass-produced.

Too bad they don't try and make something more useful and helpful with them nano-thingies, i.e. medicine, pharmaceutics, cell-repair (Ok the last one does sound Sci-Fi), etc...
But we live in a kill-first-heal-after-world right?

They've found all kinds of applications for carbon nanotubes. This is one of the latest, but probably gets a mention, because they've been trying to find a bullet proof armour that would stop bullets bruising wearers. Wikki has good details

See also, for last current applications: Timeline of carbon nanotubes
The joining of two carbon nanotubes with different electrical properties to form a diode has been proposed.
