| Abstract | O objetivo foi produzir paineis OSB com particulas de E. benthamii e mix de Pinus taeda e Pinus elliottii . O delineamento experimental envolveu cinco tratamentos compostos por paineis com tres camadas de particulas e densidade nominal de 0,65 g/cm 3 . Foram aplicados 6% de resina fenol formaldeido e 1% de emulsao de parafina. O ciclo de prensagem foi de 8 minutos, temperatura de 180 oC e pressao especifica de 40 kgf/cm 2 . Os ensaios foram realizados de acordo com a norma ASTM D1037 (1993) e a DIN 52362 (1982), sendo os resultados avaliados por meio da Analise de Variância e Teste de Scott-Knott. Como resultados, observou-se que as melhores composicoes foram obtidas no tratamento composto exclusivamente por particulas de Pinus spp e no tratamento com particulas de Pinus spp na camada central e E. benthamii nas camadas externas. Foi verificado potencial do Eucalyptus benthamii para a producao de paineis OSB quando misturada com particulas de P. taeda e P. eliiottii , tendo em vista que em paineis puros apresentou resultados insatisfatorios. Abstract Use of Eucalyptus benthamii wood in the production of Oriented Strand Boards (OSB). This research aimed to produce OSB with particles of E. benthamii and mix of Pinus taeda and Pinus elliottii . The experimental plan involved five treatments composed of panels with three layers of particles and nominal density of 0,65 g/cm 3 . The resin phenol formaldehyde and the wax sizing were applied in the amount of 6% and 1%, respectively. The pressing cycle was 8 minutes, temperature of 180 oC and specific pressure of 40 kgf/cm 2 . The assays were performed according to standard ASTM D1037 (1993) and DIN 52362 (1982) and the results were evaluated by Analysis of Variance and Scott-Knott Test. As result, it was observed that the best compositions are obtained in the treatment composed exclusively of Pinus spp particles and in the treatment with particles of Pinus spp in the core layer and the E. benthamii in the outer layers. It was verified potential of Eucalyptus benthamii for the production of OSB when mixed with particles of P. taeda and P. eliiottii , considering that in pure panels it showed unsatisfactory results.
