Abstract
Nine-ply plywood panels were produced from Eucalyptus grandisand Populus deltoidsusing urea-formaldehyde (UF) and phenol-formaldehyde (PF) adhesives. The physical and mechanical properties,such as moisture content, density, modulus of rupture (MOR) and modulus of elasticity (MOE) of the eucalyptus and poplar boards, were compared in this study. Samples were tested on both,along and across the grain. Higher values of MOR and MOEwere observed foreucalyptus as compare to poplar. Density of ply board was observed as 500-560kg.m-3in plywood from poplar and 700-720 kg.m-3in plywood from eucalyptus species. These differences were attributed to the variation in properties of veneer wood species. The effect of veneer wood species on some physical and mechanical properties of plywood was found statistically different.
