The History of Kevlar Kevlar is an organic fiber in the aromatic polyamide family. It has unique properties and a chemical composition that is its own, which distinguishes it from other man-made fibers. Kevlar is a combination of high strength, high modulus (resistance to extension), toughness and thermal stability. Kevlar has a wide range of uses. In the 1960s nylon and polyester opened the door for man-made fibers. They were cutting edge fibers in their time but to achieve maximum break strength and initial modulus, the polymer molecules needed to be in an extended-chain configuration and almost perfect crystalline packing. With flexible-chain molecules, such as nylon or polyester, this could only be done by mechanically drawn in after spinning. This required chain disentanglement and orientation in the solid phase of it....
