Kevlar - CAMEO

[DuPont] A registered trademark for a para-aramid fiber (aromatic polyamides). Kevlar® fibers are composed of poly(p-phenylene terephthalamide), which is made from p-phenylene diamine and terephthaloyl chloride.

Aramid is a shortened form of aromatic polyamide.The term was introduced in 1972, accepted in 1974 by the Federal Trade Commission of the USA as the name of a generic category of fiber distinct from nylon, and adopted by the International Standards Organisation in 1977. [citation needed]Aromatic in the name refers to the presence of aromatic rings of six carbon atoms.
