The effect of particle size and filler content on the mechanical properties of fibers-recycled low density Polyethylene composites was studied. The Date palm wood and Groundnut Shell flour were used as fillers for low density Polyethylene at 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28 and 30% wt of filler content. The study was carried out at different particle sizes of 150, 212, 250 and 300 µm of the fillers. At each of the particle size of the fillers, the mechanical properties such as ultimate tensile strength, elongation, tensile modulus, flexural Strength, flexural modulus and izod notched impact energy were determined. As the filler content increased, the tensile modulus, flexural strength, flexural modulus and izod notched impact energy increased, while the ultimate tensile strength and elongation decreased. As particle size increased, izod notched impact energy increased. Increase in particle size from 150 to 250 µm, elongation, tensile and flexural modulus and strength increased. As the particle size increased from 250 to 300 µm, elongation, tensile and flexural modulus and strength decreased. FTIR test was done on the composites. Based on the result obtained, Date palm –wood- flour showed better mechanical properties than groundnut shell flour.
