The effect of maleic anhydride grafted polypropylene (MAPP) on mechanical properties of bamboo fiber mat reinforced polypropylene composites (BMRPC) was studied. The results showed that mechanical properties of the composite depend on the amount of MAPP and those attained maximum values at 6 % MAPP. The effects of bamboo fiber mat contents on mechanical properties were also investigated. Maximum values for the tensile, flexural and impact strengths of BMRPC were obtained at a bamboo fiber mat content 45% (by weight).
