The easy definition is that Kevlar is a MAN-MADE product made from a synthetic materials called polymers, which is a strand of molecular groups called monomers. For a more precise definition see related links below
She created kevlar in 1965
A gram of kevlar thread will cost about 50 cents to a dollar. You can normally buy it in spools of thread, that can be used to make vests or hardened clothing.
I believe the answer you're looking for is, they were all invented by women, however, in the case of the bullet proof vest, a woman didn't actually invent the bullet proof vest. Stephanie Kwolek, a scientist for Dupont, devoloped Kevlar, a material used in bullet proof vests.
Yes kevlar is a smart material. Hope I helped :)

The Kevlar Vest weighs 2.5 poundsI hope this helps you!!!
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 bullet proof jacket is made from several thin layers of a material known as kevlar ( Kevlar is a registered trade mark). Kevlar is a para-aramid synthetic fibre. Some vests also allow for metal plates to be inserted. While kevlar is light-weight, inserted metal plates make the vest heavier. Though if the vest stops a bullet, I doubt the wearer would mind how heavy the vest was.
Kevlar fabric
Stephanie Kwolek developed Kevlar in 1965 while working for DuPont. DuPont owned the rights to his invention and named it after the material.
It depends on how thick the Kevlar vest is.

Because someone was tired of getting shot
Teflon is the outer material of the vest. The ACTUAL STOPPING material is more then likely going to be Kevlar.
First and foremost, it is a movie. Second, Navy SEALs do not always wear kevlar armor. It depends on the mission and the mission objectives. Sometimes the additional weight of a kevlar vest would be prohibitive.
