The particleboard industries have used a large volume of wood mainly from planted forest of Pinus, beingnecessary to diversify the wood species and optimize the use of raw material. One of the ways to optimizethe use of this resource is the utilization of the bark in the particleboard manufacturing process. In thisway, this research was developed to evaluate the physical and mechanical properties of the particleboardmanufactured with the wood of Acrocarpus fraxinifolius and different proportions of the bark. The boardswere manufactured with 100% of wood particles of Acrocarpus fraxinifolius and replacing the woodparticles with 30%, 20% and 10% of bark, board density of 0.75 g/cm³ and 8% of urea-formaldehyde resin.The properties of board density, water absorption and thickness swelling, static bending, internal bond andscrew pullout strength, were determined according to EN and NBR standards, and then compared with thestandard treatment (100% Pinus taeda) and with the minimum requirements of these standards. The resultsindicated that Acrocarpus fraxinifolius species showed technical feasibility for particleboard production and the addition of the bark until 30% did not negatively affect the physical and mechanical properties ofthe boards.
