Different surface modifiers (stearine acid and titanate coupling agent) were used to modify wood fibers. Effects of surface modified wood fibres on mechanical properties ( tensile strength and impact strength) of fibre-reinforced biodegradable composites were studied,and the tensile fracture surfaces and the interfacial adhesion of composites were examined by scanning electron microscopy,interfacial bonding mechanisms of the composites were explored,the law of change reasones of mechanical properties were analyzed. Results showed that the tensile strength and impact strength of composites improved greatly by adding stearine acid and titanate coupling agent,treatment effect of titanate coupling agent was better than that of stearine acid.
