It took over a decade to develop Kevlar, from the initial research in the 1960s to its commercial production in the 1970s. Stephanie Kwolek, a chemist at DuPont, discovered the polymer in 1965, which eventually led to the creation of Kevlar.
Yes. Stephanie Kwolek did create kevlar she was at a play and she discovered it.
Stephanie Kwolek invented Kevlar in 1965 while working as a chemist at DuPont. Kevlar is a strong and lightweight synthetic fiber that is well-known for its use in ballistic protection and other high-strength applications.
Kevlar does not have a specific expiration date, as its lifespan varies based on usage and environmental conditions. However, when properly cared for and not exposed to extreme conditions, Kevlar can last up to 5-10 years. It is recommended to regularly inspect Kevlar for signs of wear and replace it if any damage is detected.

The two monomers that form Kevlar are 1,4-phenylenediamine and terephthaloyl chloride. These monomers undergo a condensation polymerization reaction to form the long, stiff molecular chains characteristic of Kevlar.
