Bullet-proof t-shirt uses carbon nanotubes
Filed in archive Research on November 25, 2006
If you're worried about the nanotech military applications described in my last two posts, you may be able to defend yourself with a nano-enabled bullet-proof t-shirt.
Nanowerk reports that a team led by Professor Liangchi Zhang at the University of Sydney is investigating ballistic-resistance materials using carbon nanotubes.
"Especially in making bullet-proof vests, shields, and explosion proof blankets," said Zhang, "the best protective material will have a high level of elastic storage energy that will cause the projectile to bounce off or be deflected."
In his experiments, Zhang found that carbon nanotubes could be resilient to projectiles traveling at speeds of 200-1400 meters per second. The velocity of a typical rifle bullet is between 180 and 1500 meters per second. (photo of non-nano bullet-proof t-shirt LBA International)

The linked report says that "the objective is to reduce the effects of 'blunt trauma' on the wearer after being struck by a bullet." The author's journal article will have precise numbers on shock absorption.

Might stop a projectile but will it absorb the shock as well?

A piece of diamond having 1903 atoms was used as a bullet with its speed varying from 100 to 1500 m/s. The bullet dimension was selected such that the width is larger than the width of the biggest nanotube after flattening. The bullet was released from a target about 15 Â from the center axis of the nanotube and moved at a constant speed in the horizontal direction i.e., perpendicular to the nanotube axis, as shown in the graphic above. The nanotube performance was examined for bullet released with various speeds at various positions using the classical molecular dynamics method.

Will the whole impact side of the t-shirt go rigid? Sounds awesome, might make excellent space craft armor as well.
