Because a bullet-proof vest needs to be both flexible and solid at the same time - this is achieved by the chemical properties of the materials used in the construction of the vest.
No
The primary material used in bulletproof vests is Kevlar in several layers. There are many types of bulletproof vests, many of which include special inserts. The actual construction of bulletproof vests and other bulletproof clothing (they make bulletproof suit coats even!) is not really different than making other clothing items, but they adhere to a higher level of quality during construction.
yes they are
With bulletproof vests and AK47s.
Bulletproof vests are illegal in some places because they are considered to provide an advantage to criminals by protecting them from law enforcement and making it harder for authorities to stop them.
Bulletproof vests are generally worn for personal protection against bullets. They are typically worn by members of police officer SWAT teams, security guards or patrol officers.
Bulletproof or "bullet resistant" vests are usually made from Kevlar. However they may also be made from Lexan or carbon fiber composites. It is also filled with three or four layers of those material.
yes depending on moisture and light they can dry rot in 3 years
They were all invented by women .
Yes they do but in wars all the way up to the Vietnam war they didn't.

Gold is not typically used in bulletproof vests due to its high cost. Nickel is also not commonly used as it does not provide the necessary strength and ballistic protection required for bulletproof vests. Instead, materials like Kevlar, Spectra, and Dyneema are commonly used for their high strength and flexibility.
