Lester D. Shubin (September 27, 1925 – November 20, 2009) was an American research chemist who developed Kevlar for the use in ballistic vests. Kevlar's use in ballistic vests was later expanded for use in all types of personal armor.
Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
Stephanie Louise Kwolek (/ ˈ k w oʊ l ɛ k /; July 31, 1923 – June 18, 2014) was a Polish-American chemist best known for inventing Kevlar (poly-paraphenylene terephthalamide). ). Her career at the DuPont company spanned more than 40 ye
Kevlar is a registered trademark for a para-aramid synthetic fiber developed at DuPont in 1965 [1] and used commercially from the early 1970s onwards. On February 3, 2009, DuPont filed suit against Kolon for "theft of trade secrets and confidential information" relating to its product, Heracron .
In the 1980s, Dr. Jacob Lahijani, Senior Chemist at DuPont, invented Kevlar 149 and was highlighted in the "Innovation: Agent of Change. [78] Kevlar 149 is used in armor, belts, hoses, composite structures, cable sheathing, gaskets, brake pads, clutch linings, friction pads, slot insulation, phase barrier insulation, and interturn insulation.

These are used until 1971. [7] 1960s (mid) Products: William Standish Knowles and his team (at Monsanto) invent a way to selectively synthesize enantiomers via asymmetric hydrogenation. This was an important advancement because it was the first method for the catalytic production of pure chiral compounds. [15] 1968: Products
