Recently, subdivided and sophisticated industry causes energy depletion and environmental issues. That problem causes fuel efficiency and exhaustion of carbon dioxide regulation. So many company need to develop lightweight and environmental materials. CFRP(Carbon Fiber Reinforced Plastic), plastic combined with carbon fiber composite materials, was had the limelight by substitute materials because it has high specific strength and stiffness. In this paper, thermoplastic CFRP composite was manufactured by using a injection/compression molding process. Previously to manufacture using a injection/compression molding process, an experiment of thermoplastic CFRP was progressed by using a hydraulic press forming process. It was for judgment of impregnation and getting a basic properties of thermoplastic CFRP. The results of hydraulic press forming process, as the volume fraction of carbon fibers increases the tensile strength of the composite is increased. On the basis of the result of press forming results, mold for injection/compression molding process was designed. The injection/compression molding process was to make it easier to impregnate matrix to carbon fiber. The impregnation rate of thermoplastic CFRP product by used injection/compression process was not good because of frozen layer of resin. So, in order to improve this, the molded product was reproduced by insert and overmold process. It has a faster production cycle time to make thermoplastic CFRP by using a injection/compression molding process.
