Bulletproof vest

Bulletproof Vest

A bulletproof vest, also known as a ballistic vest or a bullet-resistant vest, is an item of personal protective equipment designed to absorb and reduce the impact of firearm-fired projectiles and shrapnel from explosions, and is worn on the torso. Soft vests are made from many layers of woven or laminated fibers and can protect the wearer from small-caliber handgun and shotgun projectiles, and small fragments from explosives such as hand grenades.

History

The concept of a bulletproof vest dates back to the Middle Ages, when warriors wore chain mail and plate armor to protect themselves in battle. However, the modern bulletproof vest was created in the late 19th century, with the development of materials capable of stopping bullets. The first bulletproof vests were made from silk, which was found to be resistant to bullets when tightly woven.

Design and Function

Bulletproof vests are designed to disperse the energy of a bullet over a wide area, reducing its ability to penetrate the vest. The vest absorbs the energy from the deforming bullet, bringing it to a stop before it can completely penetrate the textile matrix. Some layers may be penetrated but as the bullet deforms, the energy is absorbed by a larger and larger fiber area.

Types of Bulletproof Vests

There are two main types of bulletproof vests: soft vests and hard-plate reinforced vests. Soft vests are what most people picture when they think of a bulletproof vest. They are made of many layers of woven or laminated fibers, and can protect the wearer from small-caliber handgun and shotgun projectiles, and small fragments from explosives such as hand grenades.

Hard-plate reinforced vests are used by combat soldiers, police tactical units, and hostage rescue teams. They are typically made from metal or ceramic plates that are inserted into a fabric vest, which is then worn over the torso.

Legal Status

In many jurisdictions, it is legal for civilians to purchase and wear a bulletproof vest, unless they have been convicted of a felony. Bulletproof vests are also a regulated item in many other countries.
