Kevlar® Kevlar fiber is an aramid product (aramid) developed in 1965 by DuPont. The primary color of the fiber is yellow, strong and lightweight, and flexible, which is 5 times stronger than steel of the same weight. Kevlar is aramid fibre composed of a long chain of poly-parapherylene terephthalmide. The molecular chains are oriented in the direction of the fibers, with strong hydrogen bonding between the molecules, and the phenyl overlap between the strands makes the fibers very strong and flexible. Kevlar fiber has a planar structure that is as silky as silk. Because the ratio of carbon to oxygen in the molecule is high, the material can be flameproof, does not melt at high temperatures, and decomposes above 400 °C. Kevlar fibers have a higher density than water, and water molecules weaken the fiber strength; on the other hand, they improve the wetting properties of surface materials made from fibers. Kevlar's range of applications is similar to that of Dyneema/Spectra, but it can be used as cut-proof gloves
, marine ropes, bullet-proof helmets, bulletproof vests, and can also be used in canoes and deflated tires. Because Kevlar fibers are fire resistant, they can be used in fire protection for firefighters. However, Kevlar decomposes in the presence of alkali or chlorine. Kevlar gloves are suitable for use between -30 ° C and 160 ° C.
