In the recent years, researches on the natural fiber reinforced composites have been increasing. They are also expected as alternatives materials for traditional composites. Although natural fiber has many advantages, use of animal-based natural fibers such as silk fiber (SF) in a biocomposite material has been rarely reported. Therefore, the silk fiber reinforced poly(butylene succinate) (PBS) biodegradable composite was investigated in the present study. The mechanical properties of silk fiber reinforced PBS biodegradable composites (SF/PBS) were studied. The tensile tests of the long fiber unidirectional PBS biodegradable composites and cross-ply laminate with different fiber surface treatments were carried out. It was found that the experimental results showed that Young's modulus and the tensile strength of SF/PBS composite are the highest when using fibers with sericin removal. In analysis, Young's modulus in unidirectional composite is predictable by the rules of mixture. In addition, Young's modulus and Poisson's ratio in cross-ply laminate are predictable by the laminate theory.
