Bulletproof vests have evolved from ancient armor. In the World War I, the special forces of the United States, Germany and Italy and a few infantrymen used steel breastplates. In the 1920s, the United States developed a Bulletproof vest made of steel sheets. In the early 1940s, the United States and some Western European countries began developing bulletproof vests made of materials such as alloy steel, aluminum alloy, titanium alloy, fiberglass, ceramics, nylon, etc. In the 1960s, the US military used high-strength synthetic aramid fiber (Kevlar fiber) developed by DuPont to make bulletproof vests, which had good bulletproof effects, light weight, and comfortable wearing.

In addition to military applications, aramid fiber fabric has now been widely used as a high-tech fiber material in various aspects of the national economy such as aerospace, electromechanical, construction, automobiles, sports goods, etc.

In the field of aerospace, aramid fiber resin reinforced composite materials are used as structural materials for aerospace, rockets, and aircraft, which can reduce weight, increase payload, and save a lot of power fuel. The shell, interior decorations, and seats of Boeing aircraft have successfully used aramid 1414 material, reducing weight by 30%.

With the development of science and technology, bulletproof vests will use better performance kevlar fiber fabric materials to reduce weight, improve bulletproof effect and wear comfort, and further achieve structural modularization, variety and style serialization.
