Abstract

In the present study, we use a bamboo fiber as the reinforcement and polybutylenesuccinate (PBS) as the matrix. We fabricate long fiber unidirectional composites and cross-ply laminate with different fiber volume fractions (10, 20, 30, 40 and 50wt%). We conduct tensile tests on those composites and evaluate the mechanical properties. In addition, we measure the bamboo fiber strength distribution. We discuss experimentally-obtained properties based on the mechanical properties of constituent materials. Then, we obtain following results. Young's modulus and tensile strength in BF/PBS increase with increasing fiber weight fraction. However, the strain at fracture showed decreasing trend. Young's modulus in BF/PBS is predictable by the rules of mixture. Composites tensile strength is lower than Curtin's prediction of strength which considers distribution of fiber strength.
