what are bullet proof vests made of?

Answer 1

A material or object described as bulletproof is capable of stopping a bullet or similar high velocity missile. The term bullet resistant is often preferred since few, if any, practical materials provide complete protection against all types of bullets or multiple hits in the same location.

Such materials are usually rigid, but may be supple. They may be complex, such as Kevlar, Lexan, and carbon fiber composite materials, or they may be basic and simple, such as steel or titanium. Bullet resistant materials are often used in law enforcement and military applications, saving a number of lives.

There are strict tests which are used to classify bullet resistance, and which specify the detailed characteristics of bullets that the material or object must be resistant to. For example, the United States National Institute of Justice standard 0104.04[1] for bullet-resistant vests specifies that a Type II vest must not deform clay representing the wearer's body when hit by an 8.0 g (124 gr) 9 mm calibre round nosed full-metal jacket bullet travelling at up to 358 m/s (1175 ft/s); but a Type IIIA vest is needed for protection against the same bullet travelling at up to 427 m/s (1400 ft/s). In both cases, the vest is not required to protect against a second hit within 51 mm (2 inches) of the first.

Answer 2

It depends, if you are talking about police vests, then they are made out of kevlar and ceramics, layerd at opposing angles. If you are talking about an army vest then it has kevlar on the outside, ceramics then a steel plate in the middle, to help stop anything that gets thru. The reason for the differences in Army and Police vests is b/c of the wieght, the Kevlar and Ceramics alone wiegh about 25 pounds, while the army vest can wiegh close to 50 pounds. it is also due to the differnces in firepower.

Answer 3

Depends what you mean by 'strongest' Cast iron is very strong, but will shatter if hit by a hammer - it has little, if any ductility. Copper isnt considered strong, but can be drawn into wires that are miles long - it has a high ductility. Creating a bullet-proof vest is a question of balancing the properties of the materials used in it's construction - it would be certainly of composite construction (made of layers of differing materials) and i would not expect it to be made of a high proportion of metal - mostly due to the weight.

Answer 4

Kevlar

Answer 5

Kevlar

Answer 6

Kevlar

Answer 7

Kevlar

Answer 8

kevlar and regular nylon. the weave of kevlar is very tight and stiff so the force of a bullet is caught and disbursed over a larger area making it not penetrate. not effective for high caliber long rifles but very very effective against handguns

Answer 9

Kevlar, Spectra, Aramid fibers, - depending on level of protection titanium metal plates may be inserted. There are different levels of protection I throught IV certified by Underwriters Labs (UL).

Answer 10

Hi. Mostly Kevlar layered at different angles.
