Bulletproof Vest, also known as bulletproof vest, bulletproof vest, bulletproof vest, bulletproof clothing, individual body armor, etc., is used to protect the human body from bullets or shrapnel. Body armor is mainly composed of two parts: a jacket and a bulletproof layer. Clothes are often made of chemical fiber fabrics.
The bulletproof layer is made of metal (special steel, aluminum alloy, titanium alloy), ceramic sheet (corundum, boron carbide, silicon carbide, aluminum oxide), glass fiber reinforced plastic, nylon (PA), Kevlar (KEVLAR), ultra-high molecular weight polyethylene Fiber (DOYENTRONTEX Fiber), liquid protective materials and other materials constitute a single or composite protective structure.
The bulletproof layer can absorb the kinetic energy of bullets or shrapnel, and has obvious protective effect on low-speed bullets or shrapnel, and can reduce the damage to human chest and abdomen under the condition of controlling certain depressions.
Body armor includes infantry body armor, flight personnel body armor and artillery body armor. According to the appearance, it can also be divided into bulletproof vests, full protection bulletproof vests, women's bulletproof vests and other types.
On the one hand, the wearing performance requirements of bulletproof vests mean that under the premise of not affecting the bulletproof ability, the bulletproof vest should be as light and comfortable as possible, and people can still complete various actions more flexibly after wearing it.
On the other hand, it is the ability of clothing to regulate the microclimate environment of the "clothing-human body" system.
For body armor, it is hoped that the human body can still maintain the basic heat and moisture exchange state of "human-clothes" after wearing the body armor, so as to avoid as much as possible the accumulation of moisture on the inner surface of the body armor and cause discomfort such as stuffiness and humidity to the human body sense, reducing physical energy consumption.
In addition, due to its special use environment, the adaptability of body armor with other weapons and equipment should also be considered.
