Dec 2014 SPOTLIGHT ON Inventor of Kevlar

1946 - Kwolek earned a Bachelor of Science degree with a major in chemistry from Margaret Morrsion Carnegie College of Carnegie Mellon University. 1946 – Kwolek joined Dupont working in Buffalo New York. She moved to Wilmington, Delaware in 1950 where she continued to work for Dupont. She had planned to become a doctor but found the work interesting and decided to stay rather than pursuing a medical career. 1959 – Publishes “The Nylon Rope Trick” which demonstrated a way of producing nylon in a beaker at room temperature. It is still the basis of a common classroom experiment. 1964 - In anticipation of a gasoline shortage, Kwolek’s group began searching for a lightweight yet strong fiber to be used in tires. 1965 - Creates first of a family of synthetic fibers of exceptional strength and stiffness. Best known member of the family is Kevlar. 1971 - Modern Kevlar was introduced. Kwolek learned that the fibers could be made even stronger by heat-treating them. The polymer molecules, shaped like rods or matchsticks, are highly oriented, which gives Kevlar its extraordinary strength.

Kevlar is the registered trademark for a para-aramid synthetic fiber. Kevlar was five times stronger than steel by weight Poly-paraphenylene terephthalamide

Kevlar is used as a material in more than 200 applications

1980 - Kwolek received the Chemical Pioneer Award from the American Institute of Chemists, and an Award for Creative Invention from the American Chemical Society. 1995 – Kwolek was awarded the DuPont’s Lavoisier Medal for outstanding technical achievement. At the time of her death in 2014, she was still the only female employee to receive that honor. 1995 - Fourth woman to be added to the National Inventors Hall of Fame. 1996 - Received the National Medal of Technology and the IRI (Industrial Research Institute) Achievement Award. 1997 - Received the Perkin Medal from the American Chemical Society 2003 – Kwolek was added to the National Women's Hall of Fame. Honorary degrees by Carnegie Mellon University (2001), Worcester Polytechnic Institute (1981)[6] and Clarkson University (1997). The Royal Society of Chemistry grants a biennial 'Stephanie L Kwolek Award', "to recognise exceptional contributions to the area of materials chemistry from a scientist working outside the UK".

“All sorts of things can happen when you’re open to new ideas and playing around with things” “Not in a million years did I think the discovery of this liquid solution would save thousands of lives.”
