In this work, the produced partie'e board was one of the panel products that was made by using shells powder as filler and unsaturated polyester resin as matrix with the addition of methyl ethyl ketone peroxide as catalyst using compression molding.The purpose of this study was to investigate the mechanical properties of shells powder compounded with polyester in the manufactured particle board. Shells powder was added with different amounts of concentration (10, 20, 30, 40, 50 and 60 wt %). The addition of clam shell powder as liller was not only to utilize the waste but also to increase the hardness and strength of the particle board. Both physical and mechanical tests were conducted on the particle board. It was observed that the physical properties of the particle board increased as the amount of the filler increased but the mechanical properties decreased with the addition of shells powder up to 30 wt %. The obtained mechanical properties of panicle board were modulus of rupture (MOR) 40.911 MPa, modulus of elasticity (MOE) 180.547 MPa and internal bonding (IB) 13.605 MPa. The results of physical and mechanical properties were almost the same as the standard JISA 5908-2003 except for modulus of elasticity.
