High-performance fibers such as aramid (e.g. Kevlar) and polyethylene (e.g. Dyneema) are commonly used in making bulletproof vests due to their high strength and ability to absorb and disperse impact energy effectively. These fibers provide protection by stopping and spreading the force of a bullet, reducing the likelihood of penetration.
There are actually multiple people who warrant credit for the invention of the Kevlar bulletproof vest. The DuPont corporation developed Kevlar material. Richard Armellino marketed a Kevlar vest called the K-15 in 1975 and Richard Davis the first all Kevlar vest in 1976.
A Teflon bulletproof vest is a type of body armor that is coated with a layer of Teflon, a material known for its non-stick properties. This coating helps reduce friction and can make the vest more comfortable to wear. However, the Teflon itself does not provide any additional protection against bullets.
Today the terms are used interchangeably, but flack jackets were not always considered bullet proof. The original flak jackets were just nylon vests with steel plates, but would not necessarily stop a bullet. Now they are the same thing.
Stephanie Kwolek, a chemist at DuPont, is credited with inventing Kevlar in 1965. Kevlar is a strong synthetic fiber used in protective gear such as bulletproof vests. Kwolek's discovery has saved the lives of many people in law enforcement and military fields.

A bulletproof vest is a garment worn over the torso which protects against projectiles.
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.

A ballistic vest is another name for a bulletproof vest - a garment worn over the torso which protects against projectiles.
No
A felony
Yes.
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.
