American chemistry, inventor of kvlar synthetic fiber. He was born in New Kensington (Pennsylvania), in a family of Polish emigrants. His father wan an amateur naturalist and instilled curiosity towards the natural world from a very young age.]]> 2018-02-20 10:13:24 UTC https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/233187069 cristinacg62004 https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236376848 The first uses of Kevlar were in tires since its discovery was in the search for resistant materials for its manufacture, but now it is already used in the design of space articles, submarine cables, helmets and car brakes. In addition, the most common use is in the manufacture of bulletproof vests used by police and military worldwide.]]> 2018-02-28 13:48:51 UTC https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236376848 cristinacg62004 https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236409483 She was 42 years old when she invented Kevlar from liquid crystal polymers that, once placed in a machine, were transformed into a resistant material.]]> 2018-02-28 14:35:00 UTC https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236409483 cristinacg62004 https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236419876 In 1965, Stephanie Kwolek made an unexpected discovery that led to the creation of synthetic fibers so strong, not even steel bullets could penetrate them.]]> 2018-02-28 14:48:57 UTC https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236419876 cristinacg62004 https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236420313  During her analysis of long molecule chains at low temperatures, Kwolek observed how polyamide molecules line up to form liquid crystalline polymer solutions of exceptional strength and stiffness. That discovery made way for Kwolek’s invention of industrial fibers that today protect and save thousands of lives. ]]> 2018-02-28 14:49:35 UTC https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236420313 cristinacg62004 https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236447663 2018-02-28 15:25:08 UTC https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236447663 cristinacg62004 https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236448706 2018-02-28 15:26:33 UTC https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236448706 cristinacg62004 https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236450156 2018-02-28 15:28:23 UTC https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236450156 cristinacg62004 https://padlet.com/cristinacg62004/krvgxfi5dw5q/wish/236454998 http://www.women-inventors.com/Stephanie-Kwolek.asp
