Carbon Fiber Reinforced Plastics (CFRP), which can reduce the weight of automotive, has become the centre of attention. From the view point of improving CFRPs recycling efficiency and productivity, there is a trend that Carbon Fiber Reinforced Thermoplastics (CFRTP) is used rather than Carbon Fiber Reinforced Thermoset Plastics. Polycarbonate (PC) has a high impact strength compared to other plastics, therefore in the near future, PC is expected to replace traditional materials for automotive parts. In this study, the vacuum assisted high speed compression molding method with electron magnetic induction heating system was proposed. The good impregnation of CF/PC at short time-frame, using low melt flow rate resin, can be molded by the vacuum assisted high speed compression molding method. The fiber/matrix interfacial share strength of CF/PC was much larger than these of CF/PA and CF/PP.
