Overview.
Stephanie Kwolek developed aramids at DuPont in 1965. DuPont uses the trade name "Kevlar" for them.. 
Aramids are very present in security helmets, in splinter-resistant glass, in Ballistic vests, but also in other domains. They are used as a replacement for asbestos as a building material, for gaskets and other sealings, but also as helpers to make sails, parachutes and similar tools.
