| Resumo: | Paricá (Schizolobium amazonicum) is an amazon tropical specie with interesting physical and mechanical properties for the plywood and laminated veneer lumber industries. The aim of this pape is to assess paricá timber physical and mechanical properties used in plywood industry in the Maranhão State. Moisture content, basic and apparent densities, volumetric variation, compression strengths parallel and perpendicular to grain, shear strength, modulus of rupture and modulus of elasticity in bending, as well as modulus of compression parallel to grain were assessed. Results showed na equilibrium timber moisture content of 11,33%, a low apparent density (275,57 kg.m-3) and reduced volumetric variation (8,75%). Physical properties results were belllow than those found in the papers which considered the same specie and age. Mechanical properties assessed (compression strengths parallel and perpendicular to grain, shear strength, modulus of rupture and modulus of elasticity in bending, as well as modulus of compression parallel to grain were assessed) were also bellow average values given by literature review. Thus, paricá plywood panels are a valid alternative in comparison with similar products made of Eucalyptus, due to lower weight and dimensional stability. However, it is important to carry out actions that aim to improve the mechanical properties of paricá wood, in order to increase its strength and stiffness properties. |
