Studies on the technological potential of new species, and the parameters of the production process in the wood panel industry, are critical in view the importance of this segment. In this context, the objective this study was to evaluate the feasibility of using the Cryptomeria japonica for oriented strand board production, as well as, study the effects of panel density, resin content and composition of the layers on the quality of the final product. Eigth treatments were produced in a completely randomized design, with factorial arrangement (2×2×2), whose factors were nominal density (0.60 and 0.70 g/cm3), phenol formaldehyde resin content (4% and 6%), and percentage composition of the layers (20-60-20 and 30-40-30). The panels were pressed at 180°C of temperature, 4 MPa of pressure and 8 minutes time. The results showed that panels produced with this specie and with the parameters mentioned have satisfactory dimensional stability and mechanical properties in accordance with the minimum requirements of European Standard EN 300 for OSB panels with different uses, non-structural and structural, and in dry and humid conditions. It was concluded that wood Cryptomeria japonica presented technical feasibility for OSB production; increasing the density of the panels contributed to improving the dimensional stability and mechanical properties; the resin content not exercised great influence on the properties; and the composition of the layers 20-60-20 generated greater balancing of bending properties.
