To be exact, Kevlar is not a material name, but a registered trademark of aramid fiber produced by DuPont Company in the United States. Just like Yantai Taihe Group, Chengdu Bluestar Company, Japan Teijin Company, South Korea's Cologne, Xiaoxing Company and Taiguang Company all produce aramid fiber and have corresponding brands.

Aramid woven fabric and UD fabric used to be the main materials of bulletproof vests. However, with the increasing demands of end users for lightweight bulletproof vests and the gradual popularization and application of ultra-high molecular weight polyethylene materials, para-aramid materials are more and more used in the protective lining of bulletproof helmets and large armor backboards. More and more ultra-high molecular weight polyethylene materials are used as bullet-proof materials, and the backboard material of individual bullet-proof chest insert plate is compounded with bullet-proof ceramics.
