Keivlar Research Paper
Kevlar (C14H10N2O2)
Kevlar is used to make many different varieties of clothing, accessories, and equipment to be resistant to cuts. Kevlar is five times stronger than steel and equalling to the same weight. Kevlar is known for its use in ballistics and stab resistance body armour. Kevlar has done its part in heroism by saving the lives of thousands of people around the world.
Kevlar was invented in 1964 in a DuPort Laboratory in Delaware by a chemist named Stephanie Kwolek when she was 41. She earned a Science degree in Chemistry in 1946.
She began work at DuPort research Laboratory where she conducted low-temperature experiments for preparation of polymers for the creation of highly rigid and strong petroleum-based fibres. Kwolek made a solution that caused unstable intermediates from these experiments to bond into long chains. Under these conditions, the polymers formed a cloudy fluid in contrast to the clear and sticky …show more content…
Kevlar 's structure consists of relatively rigid molecules, which tend to form sheet-like structures that have similarities to silk proteins.
Kevlar can be used by itself or as part as o composite material to give added strength. It is best known for its use in bullet proof vests and knife proof body armour. It is also used for reinforcement in car tires, car brakes, strings of archery bows, and also in car, boat and aircraft bodies. Kevlar is used in the aircraft Apache AH-64A, this aircraft is used in the battlefield, so taking hits is unavoidable, this basic structure allows the AH-64A to receive hits and still be able to operate.
The crew and vital components are protected by armour composed of bonded boron carbide and Kevlar. When shot at, the Kevlar backing gives and expands to absorb the remaining energy and prevents the shrapnel from entering the aircraft.
Other uses of Kevlar:
Body armour (bulletproof vests,
