Resumo: Bamboo is a material used on a global scale in several areas. However, it needs adaptation in the processes for industrial use, in Brazil. The production of glued laminated panels has been growing in the world and this material can be a source of resources for this purpose. This study aimed to evaluate the physical-mechanical properties of laminated bamboo panels produced with two species (Phyllostachys aurea and Dendrocalamus asper) and two production processes/adhesives (glued-laminated bamboo and thermo-mechanical laminated bamboo). For the mechanical properties analysis, specimens removed from the panels were subjected to shear tests, Janka hardness and static bending. The same specimens were used to determine the apparent density, moisture content and degree of compression. The apparent density varied between 0.75 g cm-3 and 0.79 g cm-3, with equilibrium moisture contents between 7.83 % and 10.42 %. The highest values for the mechanical properties were verified in the thermo-mechanical laminated process. For D. asper, the modulus of rupture was 146.8 MPa, the shear glued line 6.36 MPa and the Janka hardness 3,852 N, while, for P. aurea, the modulus of elasticity reached 19,603 MPa. It was concluded that the production of bamboo laminated panels, especially using the thermo-mechanical process, can be a potential alternative. KEYWORDS: Glued-laminated bamboo, thermo-mechanical laminated bamboo, polyvinyl acetate, phenol-formaldehyde.

Contudo, necessita de aprimoramento nos processos para utilização industrial, no Brasil. A produção de painéis laminados colados está em crescimento no mundo e pode ser uma fonte de recursos para esse fim. Objetivou-se avaliar as propriedades físico-mecânicas de painéis laminados de bambu produzidos com duas espécies (Phyllostachys aurea e Dendrocalamus asper) e dois processos produtivos/adesivos (laminado colado e termomecânico). Para as análises mecânicas, corpos de prova retirados dos painéis foram submetidos a ensaios de cisalhamento, dureza Janka e flexão estática. Os mesmos corpos foram utilizados para a determinação da massa específica aparente, teor de umidade e grau de compressão. A massa específica aparente variou entre 0,75 g cm-3 e 0,79 g cm-3, com teor de umidade de equilíbrio entre 7,83 % e 10,42 %. Os maiores valores das propriedades mecânicas foram verificados no bambu laminado termomecânico. Para D. asper, o módulo de ruptura foi de 146,8 MPa, a resistência ao cisalhamento na linha de cola de 6,36 MPa e a dureza Janka atingiu 3.852 N, enquanto, para P. aurea, constatou-se 19.603 MPa no valor do módulo de elasticidade. Concluiu-se que a produção de painéis laminados de bambu, em especial no processo termomecânico, é uma potencial alternativa.
