What Chemical Elements Make Up Kevlar

The Manufacturing Process of Kevlar | kevlar

The production of Kevlar fibers is similar to the production of nylon. The first step in the production process is to produce the basic chemical (poly-para-phenylene terephthalamide) which Kevlar is made of. The second step is the process of turning the chemical into strong fibres.
