Security guards, police officers and armed forces could become Robocops able to take bullets in their stride, thanks to a carbon nanotechnology yarn which can defect projectiles without a trace of damage.
Conventional bullet-proof jackets spread the bullet's force
Conventional bullet-proof jackets, body armour and explosion-proof blankets consist of multiple layers of Kevlar, Twaron or Dyneema fibres which 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.
