Kevlar
Kevlar is the DuPont Company's brand name for a particular light but very strong aramid fibre. It was created in DuPont's labs in 1965 by Stephanie Kwolek and Herbert Blades, and Phil Thier and was first used commercially in the early 1970s. It can be spun into ropes or sheets of fabric that can either be used as-is, or used in the construction of composite components. It is now used in a wide range of applications - from bicycles to body armor - due to its high strength-to-weight ratio, five times greater than that of steel.
When Kevlar is spun in the same way that a spider spins a web, the resulting fibre has tremendous strength, and is heat- and cut-resistant. The fibres do not rust or corrode. When woven together, they form a good material for mooring lines and other underwater objects.
There are three common grades of Kevlar: Kevlar, Kevlar 29, and Kevlar 49. Kevlar is typically used as reinforcements in tires and other rubber mechanical goods. Kevlar 29 is used in industrial applications such as cables, asbestos replacement, brake lines, body armor (knife or bullet resistant). Kevlar 49 is considered to have the greatest tensile strength of all the aramids, and is used in applications such as plastic reinforcement for boat hulls, airplanes, and bikes.
Kevlar's main weaknesses are that it decomposes under alkaline conditions or when exposed to chlorine or UV light. While it can have a great tensile strength, sometimes in excess of 4.0 GPa, like all fibers it tends to buckle in compression.
