Abstract

This research was developed to evaluate the quality of homogeneous and multilayer particleboards manufactured from Melia azedarach wood and Pinus taeda with different resin contents. The experimental boards were manufactured with the nominal density of 0,75 g/cm³, using the urea-formaldehyde resin in the proportion of 6% and 8% (solid content based on oven dried wood particles) in the internal layer and 8% and 10% in the external layers. The boards were pressed at the specific pressure of 40 kgf/cm², temperature of 160ºC and press time of 8 minutes. The evaluations of the physical and mechanical properties of the boards showed the high potentiality of Melia azedarach for particleboard manufacture. The increase of resin content in the internal and external layers improved the properties of water absorption and thickness swelling. However, the mechanical properties were not affected.
