Development of integrated functions module carriers by injection molding with long glass fiber-reinforced polypropylene

摘要

We have developed injection molding technologies consisting of a new high-strength, long-glass, fiber-reinforced polypropylene (PPLGF). They are key technologies of new modular design for substantial reductions of weight and cost, offering integrated functionality. The strength of injection-molded parts is three times stronger than that of the conventional material. This technology makes it possible to replace parts from steel stamping and press-molded, glass-mat reinforced polypropylene. The front end and door modules of Atenza/Mazda6, Demio/Mazda2, RX-8 employs the module carriers using this material, resulting in dramatic weight and cost savings.
