Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
World capacity of para-aramid production was estimated at 41,000 t (40,000 long tons; 45,000 short tons) per year in 2002 and increases each year by 5–10%. [12] In 2007 this means a total production capacity of around 55,000 tonnes per year.

Although the tensile strength is similar to Kevlar, Vectran still tends to experience tensile fractures when exposed to significant stress.The wispy, hair-like fibers tend to fray, to easily acquire dirt, and to readily entangle in hook-and-loop fasteners, from which they must sometimes then be cut or (when possible) torn.
