Crushed particles of canarium schweinfurthii (Blackdate) seed shells were used to reinforce general purpose unsaturated polyester and the properties were studied in this work. Particles of sizes 0.6mm, 1.18mm and 2.36mm with each particle size having a composition weight of 100g, 150g, 180g 200g and 220g respectively were used as reinforcement. The results showed that the composite produced from particles of sizes 0.60mm and composition weight of 100g absorbed the least amount of water with percentage water absorption of 0.89%. The composite from particle size of 1.18mm had the best tensile strength and modulus of rupture of 69.95MN/m2 and 29.39MN/m2 at composition weight of 180g and 100g respectively
