'''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:
