Summary:

KEVLAR® IS THE REGISTERED TRADEMARK for one member of Du Pont's family of aromatic polyamide fibers which have been granted the generic name "aramid" by the Federal Trade Commission. It is available in three different types: KEVLAR® 49, with its high tensile strength (400,000 psi; 2760 MN/m2) and high modulus (18 million psi; 124,000 MN/m2) is designed for the reinforcement of plastics and offers industry a new level of composite performance. KEVLAR® 49 is also used in coated fabrics, ropes and cables. KEVLAR® 29, with the same high tensile strength and a modulus of 9 million psi (62,000 MN/m2), is especially well suited for a number of industrial applications including ropes, cables, coated fabrics, and protective clothing. KEVLAR® has properties similar to those of KEVLAR® 29 and is designed for the reinforcement of rubber, specifically tires, belts, and hose. This presentation, however, will concentrate on KEVLAR® 49 because of its unique combination of high strength, high modulus, and light weight, and because of its many demonstrated properties in reinforced plastics as a replacement for fiber glass.The short time since its commercial introduction in 1972 has not allowed extensive evaluation of KEVLAR® 49 and its composites for specific automotive applications. However, we believe that work in other end-uses reported here will provide valuable background information for future evaluations in the automobile industry
