Why can body armor protect against "bombs"?

A normal bullet can directly penetrate a steel plate of one to two centimeters at a certain distance. It is conceivable that how serious damage will be caused to the human body can be directly fatal.

We understand that bulletproof vests are all seen in TV series, but each plot shows us different results. Some bulletproof vests are hit by bullets and cannot cause harm to others, and some bulletproof vests are attacked by people who wear them Caused fatal injury.

BulletproofVest, also known as bulletproof vest, bulletproof vest, bulletproof vest, bulletproof suit, individual body protector, etc., is used to protect the human body from the damage of warheads or shrapnel.

The bulletproof vest is mainly composed of two parts: a jacket and a bulletproof layer.

Clothing covers are usually 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, alumina), glass steel, nylon (PA), Kevlar (KEVLAR), ultra-high molecular weight polyethylene Fiber (DOYENTRONTEX Fiber), liquid protective materials and other materials form a single or composite protective structure. The bulletproof layer can absorb the kinetic energy of the warhead or shrapnel, and has obvious protective effect on the low-speed warhead or shrapnel. It can reduce the harm to the human chest and abdomen under the control of a certain depression.
