This research was conducted to examine the effect of bonding on the bending and shear strength of COMPLY-board when used with meranti face veneer and fire retardant treated particle-board core. For ammonium sulfate, modulus of rupture (MOR) of COMPLY-board increased with increasing chemical concentration up to 10 percent and then decreased after that concentration. However, Minalith showed reverse effect to the result for ammonium sulfate. Modulus of elasticity (MOE) of COMPLY-hoard decreased with increasing chemical concentration and its differences were not significant between concentration. Shear strength was shown better when treated with ammonium sulfate than with Minalith. Wood failure of COMPLY increased with increasing chemical concentration up to 15 percent and then decreased after that concentration, The products of parallel and cross veneer laminated were better than those of COMPLY composed of fire retardant treated particleboard core. Nontreated particle-board was the least in strength. MOE of fire retardant treated COMPLY increased by 136 percent and its MOE by 170 percent as compared with non treated particle-board.
