Kevlar

History of Armor

Kevlar is five times stronger than steel but very light weight and half the wieght of fiberglass which made it ideal for making bulletproof vests. It is resistant to impact and abrasion damage. In seawwater its strength is 20 times more than steel which made it excellent for offshore drilling operations. Kevlar is made by Dupont Corporation.

Kevlar is a chemical compuned polyparaphenylene terepthalamide which belongs to the class aromatic polyamide is a para-aramid synthetic fibre. Aramides belong to class of nylons. The aramide ring and the para structure is what gives kevlar its high strength and thermal stability. Kevlar was developed in by Stephanie Kwolek and Roberto Berendt at DuPont Laboratories. Kevlar is a very strong synthetic fiber that can be spun into cloth to make body armor. Kevlar cloth was first used to make body armor in the′s. Kevlar went through a number of government tests until finally a “bullet-resistant” vest was developed.
