Natural fiber reinforced composite materials attracts attention because of a present global environment problem. Continuous natural fiber reinforced thermoplastic composites have superior mechanical property and have often been expected as structural materials. However, it is difficult to impregnate reinforcement fibers with thermoplastics because of high viscosity of melt of plastics. In this study, continuous fiber reinforced thermoplastic composites were obtained using intermediate materials fabricated through the Micro-Braiding technique. In this study uses, hemp and poly (lactic acid) (PLA) fibers were used as reinforcement and matrix, respectively. Composite plates were fabricated by hot press molding under various molding conditions, including molding temperature, pressure and time. Evaluation of mechanical properties were conducted. The relationship between the molding conditions and the mechanical properties of hemp fiber/PLA composite was obtained. It was clarified that molding temperature was most influence factor in a molding conditions.
