In this paper, we tried to fabricate new "green" composites without using artificial polymers. Their fiber orientation is unidirectional. It was shown the composites can be made by hot-pressing over 60℃. The influence of molding conditions on their tensile behavior and flexural behavior was investigated by changing the molding temperature and pressure. The molding temperature was changed every 20℃ from room temperature to 180℃. The molding pressure used was 10MPa and 50MPa. Average tensile strength and Young's modulus of the composites molded at 120℃ and 50MPa were 322MPa and 37GPa, respectively. Their Young's modulus tends to increase with increasing molding temperature. Their fractured elongation tends to decrease with increasing molding temperature over 80℃. Average flexural strength and flexural modulus of the composites molded at 140℃ and 50MPa were 386MPa and 37GPa, respectively. The relationship between fractured elongation obtained by flexural tests and molding temperature is different from that obtained by tensile tests.
