In the present study, CFRTP using thermoplastic polyimide resin as matrix was molded through a variety of molding processes to clarify the relationship between molding conditions and resin impregnation to a fiber bundle and an effect of resin impregnation behavior on the mechanical properties. The specimens were prepared using micro-braiding, film stacking and powder methods to evaluate impregnation behavior. From a cross-sectional observation and the rate of impregnation, excessive high pressure reduced impregnation and low molding pressure was enough to complete resin impregnation into the fiber bundle. In the case of the low molding pressure load, the shape of voids is changed according to molding temperature.
