In this research, the non-woven fabric by carding method was chosen for its ability to enable usage of longer carbon fiber. That was used as Carbon Fiber Reinforced Thermoplastic (CFRTP) material. It was investigated the influence of the molding conditions of heat press molding process on the mechanical properties nonwoven fabrics. Moreover, the non-woven fabric without needle-punch by carding method was developed and examined the spring-back phenomenon rate and the mechanical properties. As the results of this research, the each tendency for the tensile strength could be confirmed at temperature, pressure, time and knew that a contribution ratio at time was above all high. Moreover, the non-woven fabric which could decrease the spring-back phenomenon in cold press molding and its mechanical properties were obtained. It can hold below half of spring-back phenomenon when compared with the needle-punched non-woven fabric. Thus, it is available for molding with higher mass productivity.
