Stephanie Kwolek

Stephanie Kwolek was a famous scientist who invented a revolutionary typr of material.

She was born on 31 of July, 1923 in New Kensington, Pennsylvania. At first , she wanted to be a designer, but after some years, she decided to be a scientist because she really liked her maths and science lessons. In her middle secondary studies she chose technology.

When she finished her studies she founded her own company. One day, while she was working in her company, she discovered the kevlar.

The kevlar is a very resistant type of fiber that can resist four times the same kg as iron. It's very used by the firemen, the army and motorcyclists, and usually the police wear it in their shields. The kevlar is used too to create bullet proof vests, which can resist a lot of shots without hurting the person inside.

We think it is a great invention because it has saved a lot of lives in dangerous situations.
