She created kevlar in 1965
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.
One special property is that this polymer has a very high tensile strength. Another special property is that the Kevlar molecule has a long, tightly coiled structure, sort of like a slinky
Yes kevlar is a smart material. Hope I helped :)
Yes it does Stephanie Kwolek the creater of Kevlar invented the fiber.

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.

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.

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 would be a good choice, preferably backed with steel/ceramic inserts for extra protection.
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.
