Like bullet-proof inserts, there are many materials used to make bullet-proof shields. At present, they mainly include metals, ceramics, and pure bullet-proof fibers. The metal shield is the first to be used, and its weight is large, and its protective performance is not very high. But if you only need to deal with low-level threats, such as pistols, or if you only need to use them fixedly, it is also a good choice. With the development of material science, people have begun to use ceramics to make shields. Ceramics have better anti-ballistic properties and weight. It is much lighter than metal.
Bulletproof fibers such as PE and aramid are high-performance bulletproof materials developed in the past few decades, and they are a big leap in material application. Their appearance greatly improves the defensive ability of bulletproof shields while reducing its weight. However, the shield protection ability of pure bulletproof fiber is limited, and it cannot achieve the defense ability of rifle armor-piercing projectiles. At present, most bulletproof shields are made of ceramics and fiber materials and other materials. According to a special design, they can achieve a good protection effect.
