"KEVLAR", the oldest aramid fibre on the market, was invented and is manufactured by Du Pont de Nemours and is a market leader.
This commercial name is often used instead of the generic term "aramid fibre". This practice should be avoided. "KEVLAR", the oldest aramidefibre on the market, was invented and is manufactured by Du Pont de Nemours and is a market leader.
History : in 1965 Stéphanie Kwolek, a researcher employed by Dupont De Nemours, starting from a polymer, obtained a fibre with a modulus far in excess of any natural or synthetic fibre known at the time. In 1971 the first production factory was opened and delivered the first 200 kilograms of KEVLAR.
The properties of the fibre: extremely tough, high specific strength (strength to weight ratio), low density, good elasticity modulus, good elongation under load.
Applications : aeronautics, racing cars etc. "KEVLAR" is used for its specific properties, its transparency to radar waves, its linear behaviour and its high impact and wear tolerance.
