Kevlar Fiber:
Kevlar is the trade name of Dupont's para-aramide fibre. Kevlar Aramid fiber was commercialized by DuPont in 1972. Kevlar fiber is based on poly (P-phenylene terephthalamide). Kevlar fiber is used to make a variety of clothing, accessories, and equipment safe and cut resistant. It’s lightweight and extraordinarily strong, with five times the strength of steel on an equal-weight basis. Best known for its use in ballistic and stab-resistant body armor, Kevlar® brand Aramid fiber has shown its own heroism in helping to save the lives of thousands of people around the world.
