Progress on Stronger Carbon-Nanotube Fibers

Researchers have improved techniques for spinning fibers of carbon nanotubes: they make the nanotubes align in the fiber, creating fibers as strong as, or stronger than, materials such as Kevlar that are used in bullet-proof vests. Also, the nanotube fibers, unlike regular ropes, can be knotted without hurting their strength much. Alan Windle, a professor …
