The purpose of this study is to develop a natural fiber reinforced polymer matrix composite with high strength and stiffness, in order to apply biomass resources for practical use. A MAPP-included polypropylene resin was used as a matrix of the composite, and extruded with 5 and 10 wt% ramie short fibers. In this extrusion the composites were fabricated as a thin sheet, and treated with cyclic loading application to increase the strength and stiffness of the reinforcement. The results show that the composites were improved in tensile strength and Young's modulus after the treatment. Especially, Young's modulus of the composites increases 52% higher at 90° direction after bi-axial cyclic loading treatment. Through this treatment the composites are also improved in strength at bi-axial directions.
