What material is aramid? What is the role of aramid? Aramid (Nomex is a kind of aramid, is isophthalamide), is a new type of high-tech synthetic fiber, with ultra-high strength, high modulus and high temperature resistance, acid and alkali resistance, light weight, insulation, resistance It has excellent properties such as aging resistance and long life, and is widely used in composite materials, bulletproof products, building materials, special protective clothing, electronic equipment and other fields.

What material is aramid?

The full name of aramid is "poly-p-phenylene terephthalamide", and the English name is aramid fiber (the trade name of Teijin Aramid is Twaron, and the trade name of DuPont is Kevlar). It is a new type of high-tech synthetic fiber with excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. Its strength is 5-6 times that of steel wire, and its modulus is 2 times that of steel wire or glass fiber. ~ 3 times, the toughness is 2 times that of steel wire. The weight is only about 1/5 of the steel wire, and it does not decompose or melt at a temperature of 560 degrees. It has good insulation and anti-aging properties, and has a long service life. The discovery of aramid is considered a very important historical process in the materials industry.

What is the role of aramid?

Para-aramid fiber is an important national defense and military material. In order to meet the needs of modern warfare, the bulletproof vests of developed countries such as the United States and the United Kingdom are all made of aramid. The light weight of aramid bulletproof vests and helmets effectively increases the speed of the army. responsiveness and lethality. During the Gulf War, American and French aircraft made extensive use of aramid composites. In addition to military applications, as a high-tech fiber material, it has been widely used in various aspects of the national economy such as aerospace, electromechanical, construction, automobiles, and sporting goods. In aerospace, aramid fiber saves a lot of power and fuel due to its light weight and high strength. According to foreign data, every kilogram of weight lost during the launch of a spacecraft means a cost reduction of $1 million. . In addition, the rapid development of technology has opened up more new civil space for aramid. According to reports, aramid products are used for bulletproof vests, helmets, etc., accounting for about 7-8%, aerospace materials and sports materials account for about 40%; tire frame materials, conveyor belt materials, etc., account for about 20%, high-strength ropes and other aspects about 13%. The tire industry has also begun to use aramid cords extensively to reduce weight and reduce rolling resistance.
