In this study, the effects of ethylene-octene copolymer (EOR) and alkali treatment of bamboo fiber (BF) on the physical properties of the polypropylene (PP)/BF composite were investigated. PP/BF composites using EOR and the compatibilizer were fabricated with a twin screw extruder. Their physical properties were evaluated and the formulation was optimized. Mechanical properties, thermal degradation, and appearance of extrudate were all good for the fiber length of 200 mu m. PP/BF composites had the best physical properties when EOR-g-maleic anhydride (MAH) and PP-g-MAH were used together as a compatibilizer. When alkali treating the BF, it was observed that peaks near 1737, 1601, and 1348 cm(-1) decreased, which suggests a reduction in lignin and hemicellulose contents among the BF components and the flexural strength was enhanced. The interface adhesion properties of the PP/BF composites were identified by SEM images of the fractured surface after the tension tests.
