| Kevlar |
DID YOU KNOW THAT . . . The strongest material known to mankind is called a Kevlar? It was invented by a Polish-American chemist, Stephen Kwolek in 1971. Kevlar is a chemical compound - polyparaphenylene terepthalamide which belongs to the class aromatic polyamide - a para-aramid synthetic fibre which gives Kevlar its high strength and thermal stability. Kevlar is 5 times stronger than steel but is very light weight and half the weight of fiberglass which makes it ideal for making bulletproof vests. It is resistant to impact and abrasion damage. In seawater, its strength is 20 times more than steel which also makes it excellent for offshore drilling operations. Kevlar is made by Dupont Corporation.
