Superstrong Carbon-Nanotube Fibers

Researchers have developed a process to make carbon-nanotube fibers that are potentially strong enough to stop bullets.

Carbon nanotubes spun to form long yarnlike fibers could outperform even the strongest bullet-proof materials on the market, but turning nanotubes into such materials has proved to be a challenge. Now researchers say that they have improved the method of making the fibers: they can pull them from a hot furnace faster, make the nanotubes line up better, and vastly improve their strength. While the carbon-nanotube fibers can still be made only in small batches--and only in short lengths, experts say--the fibers show great promise for ultrastrong, resilient materials, with possible applications from body armor to oil drilling.
