Reality from fiction : Fabric that deflects bullets (Indian again)

[tweetmeme] Remember The Matrix? When Neo asks Morpheus if he was trying to tell him that he could dodge bullets and Morpheus replies “No Neo. I’m trying to tell you that when you’re ready, you won’t have to.”

If engineers at the Centre for Advanced Materials Technology, University of Sydney, have their way, then soon the cops of the world could all be attempting a Matrix scene. If not stop the bullets in mid-air, they can surely bounce them off their bodies.

Till today, bulletproof gear that cops across the world use is made up of multiple layers of Kevlar, Twaron, Spectra (Thanks Guybrush) or Dyneema fibers which offer blunt resistance to the brutal force of a bullet. They tried to stop bullets from penetrating by spreading the bullet’s force. But the people who use them can still be left with severe bruising or, worse, damage to critical organs.

The new material, however, not only stops bullets but deflects them, rather than absorbing their force. The study by engineers at the Centre for Advanced Materials Technology, University of Sydney, is published in the Institute of Physics’ journal Nanotechnology. The elasticity of carbon nanotubes means that this so called “blunt force trauma” may be avoided, say Prof Liangchi Zhang and Dr Kausala Mylvaganam. The Indian and Chinese duo who have help fortify the argument that Innovation does not happen only in the west.

The teams’ testing was done on Carbon nanotubes in the dimensions of 0.7 nanometers in thickness & 7.5 nanometers in length. Bullets made out of Diamond were fired at 1000 to 3500 meters per second at the target material and the fabric successfully bounced the bullets off of its surface. Now if diamond bullets could not make it through, then I doubt if anything else will. Engineers claim that 6 layers of such yarn, which would be about 600 nanometers thick, would be sufficient to design a fabric for practical purposes.

To say that this technology is amazing would be a gross understatement. It could prove invaluable in fighting terror across the planet.Just hope the Bad guys are not wearing the same.
