Physical and Mechanical Properties of Paricá Wood Species Treated with CCB Preservative

This research presents the production and the evaluation of particleboards manufactured with Eucalyptus grandis and oat hulls (Avena sativa), pressure bonded with castor oil based polyurethane resin (PU). Strength and stiffness properties in static bending of the panels were determined based on the standards ABNT NBR 14810:2006 [1], ANSI A208.1: 1999 [2], BS EN 312:2003 [3] and CS 236-66:1968 [4]. Analysis of variance (ANOVA) was used to evaluate the influence of the factors: mass fractions of PU resin (10, 12 and 14%) and the composition in mass fractions of Eucalyptus grandis (100, 85, 70 and 0%) and oat hulls (0, 15, 30 and 100%) in the properties modulus of elasticity (MOE) and modulus of rupture (MOR). Statistical analysis results indicated that Eucalyptus grandis and adhesive were significant in the MOE and MOR properties. However, the interaction Eucalyptus grandis-adhesive did not significantly affect the properties evaluated.
