The bulletproof performance of body armor mainly reflects the following three aspects:
(1) Anti-pistol and rifle bullets: Many soft body armors can protect against pistol bullets, but to protect against rifle bullets or higher energy bullets, ceramic or steel bulletproof plates are required.
(2) Bulletproof fragments: High-speed shrapnel produced by the explosion of various explosives such as bombs, landmines, artillery shells and grenades is one of the main threats on the battlefield. According to the investigation, the order of the threats faced by soldiers in a battlefield is: shrapnel, bullets, blast wave, and heat. Therefore, the function of the bulletproof piece must be emphasized.
(3) Prevention of non-penetrating damage: The bullet will produce a great impact after hitting the target, and the damage produced by this impact on the human body is often fatal. This kind of injury does not show penetration, but it can cause internal injuries, and severe cases can be life-threatening. Therefore, preventing non-penetrating injuries is also an important feature of body armor.
