This study aimed to evaluate the feasibility of using wood of Acrocarpus fraxinifolius, grevílea robusta, Melia azedarach, Toona ciliata, and mixture of these species for OSB manufacturing. The panels were produced in the laboratory with a nominal density of 0.80 g / cm ³, using phenol-formaldehyde resin in an amount of 6% of solid resin. There were evaluated the properties of water absorption and thickness swelling - 2 and 24 hours, internal bond, modulus of elasticity and modulus of rupture in the parallel and perpendicular direction, according to EN standards. The OSB panels produced with four species and the mixture of these species showed average values of mechanical properties above the minimum standard established by the CSA 437/1993. The results of the physical and mechanical properties obtained indicate the feasibility of the use of wood of Acrocarpus fraxinifolius, grevílea robusta, Melia azedarach and Toona ciliata, and mixture of these species for OSB manufacturing.
