Resumo de Recurso
Stephanie Kwolek
Stephanie earned a Bachelor of Science degree with a major in chemistry from Carnegie Mellon University.
She began working at DuPont in 1946.
There, she searched for a synthetic material to create a fiber that was able to withstand extreme conditions
Discovered that after being dissolved in solvent, aramid polyamides could be spun into fibers of extraordinary strength and stiffness
The material was 5x stronger than steel, extremely lightweight, and didn’t rust or corrode
This fiber was patented in 1966—DuPont named it Kevlar
She also discovered the family of synthetic fibers: poly-paraphenylene terephthalamide
Patented a method with her coworkers for preparing PBO and PBT polymers
