Kevlar invention date. In 1965 Stephanie Kwolek created the first of a family of synthetic fibers of exceptional strength and stiffness. Five times stronger than steel of the same weight, Kevlar is perhaps best known for its use by law enforcement in bullet-proof vests. S. Pound for pound, Kevlar is five times stronger than steel. The best-known member is Kevlar, a material used in protective vests as well as in boats, airplanes, ropes, cables, and much more—in total about 200 applications. Jul 31, 2018 · Stephanie Kwolek, the chemist who invented Kevlar, was born on this day in 1923. Jun 25, 2025 · Stephanie Kwolek - The bulletproof fibre from the chemistry laboratory - The invention of Kevlar – a stroke of luck - Ein Massenprodukt mit unzähligen Einsatzmöglichkeiten In 1965, the company DuPont realized that there was a need for a new type of tyre that was lightweight and durable, as a gasoline shortage was anticipated. Eventually, Kwolek discovered that her development of poly-p-Phenylene-terephthalate and polybenzamide formed an amazing fiber. Nov 9, 2018 · In 1965, Stephanie Kwolek created what we now know as Kevlar, a durable plastic that has over 200 applicable uses, including protective vests, ropes, cables, and vehicles. She dreamed of going to medical school. And it’s chemical and flame resistant. ), as part of her research into synthetic fibers for chemical company DuPont (U. Kwolek, whose invention has saved thousands of lives, was the daughter of two Polish immigrants. —died June 18, 2014, Wilmington, Delaware) was an American chemist, a pioneer in polymer research whose work yielded Kevlar, an ultrastrong and ultrathick material best known for its use in bulletproof vests. Kwolek (1923–2014) was born in New Kensington, Pennsylvania. ), it is an extremely strong, lightweight, fire-resistant, fiber that has found its way into everything from bulletproof vests and bridge cables to racing cars, lifeboats, and fishing lines. Today Kevlar® is used in boat hulls, bullet-resistant vests, cut-resistant gloves, fiber-optic cables, firefighters’ and lumberjacks’ suits, helmets, tires, sporting Stephanie Kwolek grew up loving science and sewing. Early development focused on perfecting polymerization and fiber spinning to achieve Kevlar’s exceptional strength.
