Abstract :This study examined the effects of wood pulp fiber length insert ignore into journalissuearticles values(short, medium, and long);, and fiber loading insert ignore into journalissuearticles values(27%, 37%, 47%, and 0% [non-reinforced PP]); with 3% maleic anhydride-grafted polypropylene on the mechanical properties of wood-plastic composites insert ignore into journalissuearticles values(WPCs);. Polypropylene and fibers were compounded into pellets using a counter-rotating twin-screw extruder and test specimens were prepared by injection molding. The results show that increases in fiber length and fiber loading significantly increased insert ignore into journalissuearticles values(P < 0.05); the mechanical properties of the WPCs insert ignore into journalissuearticles values(MOE and tensile modulus);. The behavior of the composites against MOR and impact strength varied according to fiber length and loading level. In general, the tensile strength was observed to be the same.
