The presents preparation and characterization of different types of lignocellulosic fillers (pine wood saw-dust/ walnut shell flour/ black rice husk powder) reinforced polypropylene composites were presented. The effect of MAPP as coupling agent (4wt％) on the physical and mechanical properties was also investigated. Polypropylene composites were prepared at different rates of filler/matrix (wt％) by using extrusion (for melt blending) and hot compression molding process. Maximum values of tensile and flexural strength were obtained as 26.1 and 43.4 MPa, respectively, whereas the elongation at break value was 4.11％ at 10％ pine wood sawdust reinforced PP. Tensile and flexural modulus of composites reached the max-imum values as 3855 and 3633 MPa with the composite of 30％ walnut shell flour reinforced PP. Characterization of compos-ites was carried out by using tensile test, flexural test, FT-IR, and SEM.
