Natural fibers play an important role of alternatives of glass fibers that have been main components of polymer composites. In our study we try to investigate the mechanical and sound insulation properties of polypropylene composite containing Bamboo Powder (BP). In order to improve the poor interfacial adhesion between the natural fibers and the matrix PP, maleic anhydride grafted PP (MAHPP) was used as a compatibilizer. The degree of coupling between PP and MAHPP was confirmed by FT-IR and the dispersibility of BP within the PP matrix was analyzed by SEM. Also, it was found that the tensile strength was increased with adding amount of MAHPP up to 9wt% because the interfacial adhesion was enhanced between BP and PP matrix. Further we will observe that the effect of various bamboo powder`s dispersion state and their amount on sound insulation through transmission loss test.
