- Jun 28, 2017 -

The bulletproof vest is a protective suit like armor used to reduce the damage of bullets, which are equipped by the police and the army. These vests are widely guarded from pistols fired pistol ammunition - the same regardless of type, style, material, and pistol ammunition caliber.

The above name is more or less misleading, because most of these protective clothing for the large caliber rifle or rifle only little or no protection, regardless of the type of bulletproof vest, style, material, or rifle the caliber (this exception can not In general terms .22 LR type, which can usually protect against large caliber rifles, rifle guns.) These bulletproof vest are widely guarded from pistols fired pistol ammunition - also regardless of type, style, material, and pistol ammunition caliber.

Some types of bulletproof vest have metal extensions (steel or titanium) that can be added to some important parts of the body to add some ceramic or polyethylene sheets to increase protection. If the bullet hit the filler, these protections can effectively protect all pistols and some rifles. This kind of vest has become a standard in military use as a forward in the ballistic technology so that the "Kevlar-only" vest failure - the CRISAT NATO standard for vests includes African backing. Some vests are also designed to protect against knife attacks. As an important personal protective equipment, bulletproof vest experienced a transition from a metal armor shield to a nonmetallic composite material, and a process of developing a composite system from synthetic materials to synthetic materials and metal armor plates and ceramic panels. The prototype of the human armor can be traced back to ancient times, the original nation to prevent the body was hurt, had a natural fiber braid as a chest care material. The development of weapons forcing the human armor must have the corresponding progress. As early as the late 19th century, silk used in medieval armor in Japan was also used in American-made body armor. In 1901, after President William McKenley was assassinated, body armor caused the attention of the US Congress.

Although this bulletproof vest can prevent low-speed pistol bullets (speed of 122 m / s), but can not prevent rifle bullets. Thus, in the first world war, there have been natural fiber fabric for the clothing lining, together with the steel plate made of bulletproof vest.
