Chapas de madeira aglomerada de uma camada de Pinus elliottii Engelm com a adição das cascas de Eucalyptus pellita F. Muell

Abstract

This paper evaluated the physical and mechanical properties of particleboards manufactured with Eucalyptus pellita bark added to Pinus elliottii wood. The mechanical properties evaluated were static bending (modulus of rupture and modulus of elasticity) and tensile strength perpendicular to surface, while the physical ones were thickness swelling and water absorption. Ureaformaldehyde PB 2346 adhesive was used in the rates of 6% and 8%, in particleboard manufacturing. The bark/wood rates were: 0/100, 10/90, 20/100 and 30/70, with three repetitions to each treatment. Bark inclusion into particleboard production showed to be technically possible, according to physical and mechanical results obtained.
