Abstract
Wood of Paricá species <i>(Schizolobium amazonicum</i>) is highly susceptible to degradation by decay microorganisms. Due to its increasing production in the northern region of Brazil, about 85 thousand hectares, and later use both for structural purposes and for the furniture industry, the need of extending life of Paricá wood applying chemical preservatives arises. One current alternative is the treatment by autoclave using CCB (Copper Chrome Boron). The aim of this study was to evaluate the influence of treatment with CCB in the properties: apparent density, parallel and perpendicular hardness to the grain, strength to shear and in the compression parallel to the grain of the <i>Schizolobium amazonicum</i> wood species, comparing the results with untreated wood. We observed that treatment with CCB did not change the properties of apparent density, shear strength, perpendicular hardness, strength and stiffness in compression parallel to the grain. For the hardness strength parallel to the grain was decreased in 28.9%.
