At present, aramid fiber is an important material for national defense and military industry. In order to meet the needs of modern wars, the bulletproof vests in developed countries such as the United States and Britain are all made of aramid fiber. The lightweight of aramid bulletproof vests and helmets has effectively improved the rapid response ability and lethality of the army. In the Gulf War, aramid composites were widely used in American and French aircraft. In addition to military applications, it has been widely used as a high-tech fiber material in aerospace, electromechanical, construction, automobiles, sporting goods and other aspects of the national economy. In aviation and aerospace, aramid fiber saves a lot of power fuel because of its light weight and high strength. According to foreign data, every kilogram of weight is reduced during the launch of spacecraft, which means that the cost is reduced by 1 million dollars. In addition, the rapid development of science and technology is opening up more new civil space for aramid fiber. It is reported that aramid products account for about 7-8% of bulletproof vests and helmets, and aerospace materials and sports materials account for about 40%. Tire skeleton materials and conveyor belt materials account for about 20%, and high-strength ropes account for about 13%. The tire industry has also begun to use a large number of aramid cords to reduce weight and rolling resistance.
