Commonly used bulletproof equipment mainly includes bulletproof vests, bulletproof shields and bulletproof helmets. It is an individual soldier's body protection equipment, used to effectively protect oneself from the damage caused by bullets and bullets to the human body. Bulletproof equipment is not only of great significance in large-scale wars, but in peacetime, it is also an indispensable protective equipment for military and police personnel to maintain social security and stability.
With the widespread application of modern high-tech means in the military, weapons are becoming more and more powerful, which to a certain extent requires higher and higher requirements for bulletproof materials.
From the material point of view, body armor can be divided into three types: software, hardware and soft-hard composite. Bulletproof vests are mainly composed of two parts: a jacket and a bulletproof layer. The jacket is usually made of chemical fiber fabrics. The bulletproof layer is made of metal (special steel, aluminum alloy, titanium alloy), ceramic sheets (corundum, boron carbide, silicon carbide, alumina), Fiberglass, nylon (PA), Kevlar (KEVLAR), ultra-high molecular weight polyethylene fiber (DOYENTRONTEX Fiber), liquid protective materials, polyimide fiber (PI) and other materials form a single or composite protective structure.
Bulletproof shields are mostly rectangular and curved sheet objects, usually with handles on the back that are easy to hold. As an extremely effective bulletproof equipment, it can be used with body armor to achieve the best effect. The more common bulletproof shields in China are handheld bulletproof shields and wheeled bulletproof shields.
The handheld bulletproof shield is made of super-strong fiber materials such as Kevlar aramid and high-strength flame-retardant fiberglass using a special process. The product is light and flexible, has good comprehensive ballistic resistance and a high level of ballistic resistance.
The wheeled bulletproof shield is made of high-quality bulletproof steel plates. The mobile structure of the shield is composed of three universal wheels. It can advance quickly, turn flexibly, and is more convenient to use. It is often used to set up checkpoints at troop posts, military defense areas and important areas.
The bulletproof helmet is composed of a helmet shell (including edges) and a suspension buffer system (including hood hoops, buffer layers, chin straps, and connectors). The helmet shell is laminated and formed from aramid-impregnated woven fabric. It should be comfortable and stable to wear.
In addition to bulletproof capabilities, the design of bulletproof helmets also needs to take into account the mobility of the wearer's head. The best ballistic helmets can withstand Class 3A attacks (can stop bullets fired from a .44 Magnum revolver).
In addition, most bulletproof helmets can be equipped with communication equipment and night vision equipment, which can not only reduce the impact of stun bomb explosions or gunfire sounds on personnel's eardrums, but also help team members maintain communication with teammates or headquarters in high-decibel noise environments. contact.
