   What is Kevlar ®?

   • Created by Stephanie Kwolek, DuPont ™ Kevlar ® is a heat-resistant para-aramid synthetic fiber with a molecular structure of many inter-chain bonds that make Kevlar ® incredibly strong. Best known for its use in ballistic body armor, Kevlar ® also has many other applications because of its high tensile strength-to-weight ratio.

   What is Kevlar aramid?

   • Kevlar fiber has a tensile strength comparable with that of carbon fiber, a modulus between those of glass and carbon fibers and lower density than both. Kevlar aramid is used for high-performance composite applications where lightweight, high strength and stiffness, damage resistance, and resistance to fatigue and stress rupture are important.

   Kevlar is a synthetic fiber that is in the aramid fiber’s group which is heat resistant. Kevlar and Nomex are a part of this group. Synthetic fibers are fibers synthesized through chemical synthesis, as opposed to natural fibers derived from living organisms. Synthetic fibers are created by extruding fiber-forming material through spinnerets, forming fiber.
