Now, a super-light nanotube armour that is 7 times stronger than steel of same weight
A US company has unveiled a super lightweight armour made of carbon nanotubes that is seven times stronger than steel of the same weight, and conducts almost as well as aluminium.
The company has said the material could lead to lighter bulletproof clothing, wiring for aircraft and more efficient power transmission.
Scientists have known for long that carbon nanotubes have extraordinary strength, transmit heat well and can act as semiconductors, depending on the method of construction.
But these properties are of limited value in individual tubes and making bulk material with the same properties has not proved easy.
