DuPont researcher Stephanie Kwolek gained a measure of celebrity among that subset of Americans interested in innovation in 1966 when she patented a spun polymer called Kevlar, which she had created in 1965.
Kevlar is a lightweight, strong, non-corrosive, water and fire-resistant fiber created from long parallel polymeric chains.
Probably its best-known use has been in bulletproof vests, used mainly by the police and the military. Other applications have been in tires, sails, ropes, gloves, protective outfits for firefighters, kayaks, skis, helmets,drum heads, and aircraft shielding.
