Like Nomex, Kevlar is a distant relative of nylon, the first commercially successful "superpolyamide", developed by DuPont in the 1930s. Kevlar was introduced in 1971, having been discovered in the early 1960s by US chemist Stephanie Kwolek (1923-2014), who earned US Patent 3,287,323 for her invention

Kevlar is used in the making of bulletproof vests, helmets and other lightweight military equipment. Riding shoes, firefighting apparel, body armor and body pads also rely on Kevlar's unique qualities. Kevlar is a type of plastic with a very high tensile strength. The molecules are aligned parallel to each other and are very tightly bound

Technical Guide. DuPont™ Kevlar® is an organic fiber in the aromatic polyamide family. The unique properties and distinct chemical composition of wholly aromatic polyamides (aramids) distinguish them - and especially Kevlar® - from other commercial, man-made fibers. Kevlar® has a unique combination of high strength, high modulus, toughness
