New fiber is tougher than Kevlar2010-12-06 12:02 by DanielaTags: Fiber, Kevlar
Researchers at Northwestern University have nanoengineered a new kind of fiber that they say is tougher than Kevlar. With Department of Defense funding, the team has created a a high performance fiber from carbon nanotubes that they say is remarkably tough, strong, and resistant to failure. "A big issue in engineering fibers is that they are either strong or ductile — we want a fiber that is both," says says professor Horacio Espinosa. "The fibers we fabricated show very high ductility and a very high toughness. They can absorb and dissipate large amounts of energy before failure. We also observed that the strength of the material stays very, very high, which has not been shown before. These fibers can be used for a wide variety of defense and aerospace applications." These include bulletproof vests, parachutes, or composite materials for use in vehicles, airplanes and satellites. Read more -here-
