Plywood becomes very important material for various structural purposes in Bangladesh and used as a substitute of solid wood. Therefore, the objective of this study was to determine and compare the physical and mechanical properties of plywood produced with veneers of eucalyptus and simul tree. The commercial urea formaldehyde resin was used for fabricating the panels. Physical properties i.e., density, moisture content, water absorption and thickness swelling; and mechanical properties i.e., modulus of elasticity (MOE) and modulus of rupture (MOR) of the panels were determined according to the procedure of ASTM standards. It was found that the density of eucalyptus and simul plywood was 879 and 536 kg/m3 respectively. Further, it was also observed that MOE and MOR of eucalyptus plywood were almost 2 and 2.5 times higher respectively than those of simul plywood. These differences were attributed to the variation in properties of veneer wood species and the effect of veneer wood species on some physical and mechanical properties of plywood was found statistically different.
