WASHINGTON: The woman who invented Kevlar – a super-strong fibre that revolutionised body armour - has died at the age of 90.
Stephanie Kwolek died in a hospice, media sources said, citing her friend and former co-worker Rita Vasta, who did not give a cause of death. She was 90.
Kwolek was working for the US chemical company DuPont when she invented Kevlar.
"We are all saddened at the passing of DuPont scientist Stephanie Kwolek, a creative and determined chemist and a true pioneer for women in science," DuPont CEO Ellen Kullman said in a statement.
"She leaves a wonderful legacy of thousands of lives saved and countless injuries prevented by products made possible by her discovery."
Kwolek invented Kevlar in the 1960s in what she once called "a case of serendipity".
She was looking for a material that could be used to reinforce car tyres that was lighter weight and more fuel-efficient than the metal previously in use.
The liquid crystal polymer she created became Kevlar, which is five times stronger than steel and extremely lightweight.
Today, the fibre is used in body armour as well as sporting gear, boats, and in puncture-resistant tyres.
Kwolek in 1996 was awarded the National Medal of Technology and Innovation "for her contributions to the discovery, development and liquid crystal processing of high-performance aramid fibers which provide new products worldwide to save lives and benefit humankind".
