-'''Kevlar''' is the registered trade mark of a para-aramid ([[aromatic polyamide]]) fiber produced by [[DuPont]] Chemical Company. [[Chemist]]s Stephanie Kwolek and Herbert Blades first synthesized Kevlar in 1965, and Kwolek [[patent]]ed the fiber in 1966. Fibers of Kevlar consist of long [[molecule|molecular]] chains produced from '''poly-paraphenylene terephthalamide'''. The chains are highly oriented with strong interchain bonding, which results in a unique combination of properties, including:

-*high tensile strength at low weight (five times stronger than the same weight of [[steel]])
-*low [[density]]
-*low [[electrical]] conductivity
-*high [[chemical]] resistance
-*low thermal shrinkage
-*excellent [[dimensional stability]]
-*high [[cut resistance]]
-*flame resistant
-*self-extinguishing
-Kevlar does not rust nor [[corrosion|corrode]] and is used in bullet proof vests, underwater cables, brake linings, space vehicles, boats, parachutes, skis, and building materials.
