LIGHTER & LIGHTER

Among the automobile applications discussed here are DuPont's Kevlar, are aramid fiber, used for belts for radial tires and mechanical rubber good such as belts and hoses; in Denmark Kevlar prototype brake pads and clutch plates are being tested. At the Ford Motor Company, a sink-resistant plastic has been developed with a thermoplastic additive to temper the tendency of polyester sheet molding compound to shrink and sink; reinforcement is provided by short (0.5in) glass fibers for the undesirable of a truck hood and long (2in) glass fibers for the surface. Ford is also experimenting with a graphite-fiber reinforced composite part. It is reported that General Electric has developed epoxy resins which will be able to handle a number of processes including: compression; transfer, injection, reaction injection molding (RIM) and reinforced reaction injection molding (RRIM); pultrusion; filament winding; and liquid molding with a minimum amount of processing problems. General Motors' most widely used resin is polypropylene -- 230 million lb (104 million kg) of it will be used in 1979. It's followed by urethane (foam and RIM), ABS and PVC. A 1980 Dodge Mirada CMX is almost 450 lb lighter than earlier models of its type, thanks mainly to expanded use of plastics.
