Carbon Nanotube SuperFabric - ASME

Carbon nanotubes have a measured strength about 50 times that of carbon steel. Because of differences in the way the familiar chicken-wire patterns of carbon atoms line up across the surface, nanotubes can either act as metals or semiconductors. Threads as thin as a human hair are stronger than Kevlar and tougher than spider silk. Extraordinary strength and lightness of woven nanotube sheets ...
