She created kevlar in 1965
Yes kevlar is a smart material. Hope I helped :)
Yes it does Stephanie Kwolek the creater of Kevlar invented the fiber.
No, Kevlar is a para-aramid synthetic fiber. Basically a really really tough cloth-like material. Polycarbonate products, such as Lexan windows, are very hard and rigid. They can be molded to fit a specific application but are not flexible like Kevlar is.
Kevlar is 'pure' in the sense that it is not a mixture or alloy, but a lattice of poly-paraphenylene terephthalamide monomers.
Kevlar was developed by a Polish-American scientist named Stephanie Kwolek at DuPont in 1965. In the 1970's it replaced steel in racing tires. Today it is used in many things such as, tires, racing sails, and body armor.
