Research Abstract

A green composite composed of, short ramie fiber and polypropylene (PP) was produced. To improve the mechanical properties, equi-biaxial cyclic tensile loading was applied for this material. After the loading, tensile strength and Young’s modulus of the specimens, which were cut-out from the cyclic-loaded material, were improved to approximately 5% to 10%. It was clarified for the first time in the field of green composites that the green composite is strengthened with isotropy through this method.
