The mechanical properties consist of modulus of rupture, modulus of elasticity and internal bonding and physical behaviors such as water absorption and thickness swelling of panels were determined. Results showed that with increasing the density of panels and press temperature modulus of rupture, modulus of elasticity and internal bonding of panels increased, while bending strengths of panels were differently affected by press closing speed compared to the internal bonding, so that with increasing the press closing speed modulus of rupture increased, but internal bonding decreased. Moreover, increasing panel density and press temperature, water absorption and thickness swelling of panels decreased. The press closing speed affected the water absorption and thickness swelling, insignificantly. 2016 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48544479017 en http://www.redalyc.org/revista.oa?id=485 Maderas.
