Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
Stephanie Louise Kwolek (/ ˈ k w oʊ l ɛ k /; July 31, 1923 – June 18, 2014) was a Polish-American chemist best known for inventing Kevlar (poly-paraphenylene terephthalamide). ). Her career at the DuPont company spanned more than 40 ye
Kevlar was initially used as a replacement for steel-belting in tires, and later for use in ropes, gaskets, and automotive and aviation parts. [1] [3] In 1971, Shubin, who was then the Director of Science and Technology for the National Institute for Law Enforcement and Criminal Justice, [4] suggested using Kevlar to replace nylon in bullet ...
In the 1980s, Dr. Jacob Lahijani, Senior Chemist at DuPont, invented Kevlar 149 and was highlighted in the "Innovation: Agent of Change. [78] Kevlar 149 is used in armor, belts, hoses, composite structures, cable sheathing, gaskets, brake pads, clutch linings, friction pads, slot insulation, phase barrier insulation, and interturn insulation.
