How does a bullet proof vest?
Understanding this is important, especially if you plan to put your life on the line and depends on your vest for protection against threats.
The first is a bullet proof vest is usually what is considered soft body armor. Hard body armor is made of metal or ceramic tiles, while a bullet proof vest is made usually of Kevlar. How any soft actually prevents a bullet, but? A West of Kevlar or gold Flex is essentially a very strong (but easy) ballistic network of fibre that resists force of a bullet. When a ball hits the ' net ", distance pieces of netting material sufficient to absorb and disperse their energy, to keep it from penetrating straight through the material.
The West has, however, that more than just protect against penetration by a bullet. Blunt force trauma is also an issue here. Easy to keep from going through the vest is not enough. Point is sufficient to cause serious injuries although the vest keeps the body in point from going. A contemporary vest may protect the wearer from this threat, and allow them to return fire.
How these vest work to stop the blunt force trauma is much the same as the road ends at a point. It dissipates the energy through the mesh material. This requires, however, that the fibers of the material must be twisted very tightly and woven together correctly. Resin and plastic film are also used to provide a vest more resistance to blunt force trauma. The effect of these models is that while the effect is still noticeable, the force is spread over the whole surface of the vest, rather than being concentrated in one place, which could break a bone or even damage the internal organs.
Bullet proof vest pattern designated as one of seven categories of the National Institute of Justice. All these categories have special protection rating (caliber of the point that they can stop). Hard armor ballistic plates can also be added to increase the protection level of threat for vest-level III and level IV, which are designed to take high-caliber hits from rifle rounds. It is therefore important that you choose the correct category of proof vest for the point of threats that face you before making a purchasing decision.
