Carbon Fiber Reinforced Plastic (CFRP) is used for purposes which require high specific intensity, but the materials and molding for CFRP are relatively expensive in general and molding takes a long time. This research applies the pultrusion method utilized in Glass Fiber Reinforced Plastic (GFRP) to CFRP, aiming to achieve low-cost and high-speed molding. In addition, we conducted a simulation of the viscosity distribution of resin inside the mold in order to extract the optimum molding conditions with the minimum number of prototypes. As a result, we successfully molded a satisfactory CFRP prismatic pipe after only 2 prototypes.
