Kevlar is the registered trademark for a para-aramid synthetic fiber, related to other aramids such as Nomex and Technora. This high-strength material was first commercially used in the early 1970s as a replacement for steel in racing tires. In fact, its tensile strength is five times than that of steel, making it way more stronger than steel. It is used an unusually lightweight and durable new fiber which was later developed by DuPont into the synthetic Kevlar, which is used in everything from military helmets and bulletproof vests to work-gloves, sports equipment, fiber-optic cables and building materials.
