- Carbon Fiber Reinforced Plastics (CFRP) is superior in the specific tensile strength and the specific rigidity which used for various products in aerospace and sports industry. With increasing attention to Carbon Neutral (CN) in the world, the vehicle electrification and the lightweight are expanding. As a result, the application of CFRP to luxury cars, electric cars and sports cars, is increasing. It is also applied by Lexus LC, RC-F and Toyota 86 GRMN. However, there are two technical concerns. First is the durability which caused by CFRP resin characteristic. Second is poor appearance which is caused by CFRP surface pinholes. In order to secure the good durability and surface appearance, CFRP must be required pre-treatment before painting (putty applying a filler for the plastics surface coverage and surface sanding) and the multiple painting. Current painted CFRP is not suitable for the mass production due to long and complicated process. As a result, the applied vehicle is limited. In this report, we will explain the In Mold Coating (IMC) paint and molding process, it can manufacture Carbon Fiber Sheet Molding Compound (C-SMC) roof molding, painting at once.
