Hybrid wood veneer panels and particleboards for structural use

Abstract The use of wood panels has been gaining prominence in the construction industry. MDP panels do not meet structural requirements, unlike OSB and plywood panels. An alternative solution to improve the use of wood particleboard is the reinforcement of wood particleboards (hybrid panels). This research study aimed to evaluate the potential of using hybrid panels made with wood particles and veneers of Pinus sp. and with castor-based bicomponent polyurethane resin, meeting the Brazilian Standard ABNT NBR 14810-2. The physical and mechanical properties results were compared with the normative requirements for OSB (EN 300) and plywood panels (DIN 68792), as well as with the results of commercial plywood OSB panels. Hybrid panels met the standard requirements for OSB and plywood commercial panels indicated for structural use. The statistical analysis indicated the superiority of the physical and mechanical properties of the hybrid panels when compared to the results of the OSB and commercial plywood panels, a result that is also due to the use of the castor resin.
