Body Armor – General Thoughts:

Due to the various types of projectile, it is often inaccurate to refer to a particular product as “bulletproof” because this implies that it will protect against any and all threats. Instead, the term bullet resistant is generally preferred.

Types of Body Armor:

Soft:

Made from many layers of woven or laminated fibers and can be capable of protecting the wearer from small-caliber handgun and shotgun projectiles, and small fragments from explosives such as hand grenades. use layers of very strong fiber to “catch” and deform a bullet, mushrooming it into a dish shape, and spreading its force over a larger portion of the vest fiber. 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. While a vest can prevent bullet penetration, the vest and wearer still absorb the bullet’s energy. Even without penetration, modern pistol bullets contain enough energy to cause blunt force trauma under the impact point.
