Abstract

This work evaluated the physical and mechanical properties of three-layer particleboard manufactured with Eucalyptus pellita bark and Pinus elliottii wood. The mechanical properties evaluated were static bending (modulus of rupture and modulus of elasticity) and internal bonding, while physical ones were water absorption and thickness swelling. Three different bark and wood compositions in the core and on the layers were evaluated: one without bark and two with bark. It was even studied the addition or not of 1% of paraffin (over the particles dry weight), resulting in six treatments, each one with four repetitions. There were showed better results of MOR, MOE e LI among the treatments with bark and without paraffin than in those with bark and paraffin.
