   Kevlar (para-aramid) 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.

   Who invented Kevlar?

   • Poly-paraphenylene terephthalamide (K29) – branded Kevlar – was invented by the American chemist Stephanie Kwolek while working for DuPont, in anticipation of a gasoline shortage. In 1964, her group began searching for a new lightweight strong fiber to use for light, but strong, tires.

   Why is Kevlar so popular?

   • Kevlar. In 1964, Kwolek's research group was tasked with finding a fiber to make durable, lightweight tires to improve fuel efficiency in cars. It got to be a race, but it was a very, very, very secretive race. So that very few people outside of our laboratory knew what was going on. But it still was a lot of fun, particularly if you want.

   How strong is Kevlar?

   • Molecular structure of Kevlar: bold represents a monomer unit, dashed lines indicate hydrogen bonds. When Kevlar is spun, the resulting fiber has a tensile strength of about 3,620 MPa (525,000 psi), and a relative density of 1.44 (0.052 lb/in 3 ). The polymer owes its high strength to the many inter-chain bonds.
