Aramid fiber is called poly benzene two phenylene terephthalamide completely, and Aramid fiber is English, is a novel high-tech synthetic fiber, has super high strength, high modulus and high temperature resistance, acid and alkali resistance, light weight, insulation, ageing resistance, long life cycle and other excellent performances, the strength of the Aramid fiber is 5-6 times of that of a steel wire, the modulus of the Aramid fiber is 2-3 times of that of the steel wire or glass fiber, the toughness of the Aramid fiber is 2 times of that of the steel wire, the weight of the Aramid fiber is only about 1/5 of the steel wire, and the Aramid fiber is not decomposed and melted at the temperature of 560 ℃. It has good insulating property and ageing resistance, and has long life cycle. The discovery of aramid fibers is considered to be a very important historical process in the material world. The composite material is widely applied to the fields of composite materials, bulletproof products, building materials, special protective clothing, electronic equipment and the like.
In the textile field, aramid fibers can be made into body armor, bulletproof helmets, bulletproof vests, individual protective articles such as fire uniforms, fire masks, military and police training clothes, cutting-proof gloves and the like; in the civil field, the aramid fiber can be made into flame-retardant interior decorations and fabrics of airplanes, automobiles and high-speed rails, and can be made into fire blankets, escape ropes, flame-retardant curtains, bedspreads, pajamas, tablecloths, aprons, microwave oven gloves and the like. Aramid fiber is an important national defense and military material, in order to meet the requirements of modern wars, body armor of developed countries such as America, English and the like is made of aramid fiber, and the aramid fiber body armor and helmets are light in weight, so that the rapid response capability and the killing power of military are effectively improved.
