The unique properties and distinct chemical composition of wholly aromatic polyamides (aramids) distinguish them—and especially Kevlar®—from other commercial, man-made fibers. Kevlar® has a unique combination of high strength, high modulus, toughness and thermal stability.
Aramid - Wikipedia
Aramid fibers, short for aromatic polyamide, are a class of heat-resistant and strong synthetic fibers. They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in marine cordage , marine hull reinforcement, as an asbestos substitute, [ 1 ] and in various lightweight consumer items ...
