Resumo: The aim of this research was to evaluate the physical and mechanical properties of cross-glued laminated wood (MLCC) and cross-glued laminated bamboo (BLCC) panels. For the bonding of veneers of wood (Eucalyptus grandis and Hevea brasiliensis) and bamboo (Dendrocalamus giganteus) an adhesive based on resorcinol-formaldehyde (RF) was used in ratio 350 g.cm-2 per double line of glue. The slides were cold pressed under a pressure of 1MPa at room temperature for a period of 24 hours. Three species-based treatments were adopted: 1) eucalyptus lamellae; 2) rubber tree coverslips; 3) Bamboo Coverslips. Bulk density, moisture content, water absorption, static bending modulus of elasticity (MOE) and modulus of rupture (MOR) parallel and perpendicular and shear strength in the glue line were evaluated. The results of the chemical analysis indicated a higher content of extractives and lignin for eucalyptus. Bamboo had the highest density, differing significantly from the others. The rubber tree MLCC panels showed lower moisture content and higher water absorption rate. For the parallel MOE property, the rubber tree MLCC panels showed a higher mean value while the perpendicular MOR of the bamboo panels showed a higher mean value. For shear strength in the glue line, all evaluated treatments met the normative requirements of EN-314-2:1993. Among the species analyzed, bamboo is recommended, which has shown great potential for the manufacture of MLCC, in addition to representing a sustainable option for the future.

Para el pegado de chapas de madera (Eucalyptus grandis y Hevea brasiliensis) y bambú (Dendrocalamus giganteus) se utilizó un adhesivo a base de resorcinol-formaldehído (RF) usó en proporción de 350 g.cm-2 por doble línea de cola. Los portaobjetos se prensaron en frío a una presión de 1 MPa a temperatura ambiente durante un período de 24 horas. Se adoptaron tres tratamientos basados ​​en especies: 1) laminillas de eucalipto; 2) laminillas árbol del caucho; 3) laminillas bambú. Se evaluó la densidad aparente, el contenido de humedad, la absorción de agua, el módulo de elasticidad de flexión estática (MOE) y el módulo de ruptura (MOR) en paralelo y perpendicular y la resistencia al corte en la línea de cola. Los resultados del análisis químico indicaron un mayor contenido de extractos y lignina para eucalipto. El bambú fue el de mayor densidad, diferenciándose significativamente de los demás. Los paneles MLCC de árbol de caucho mostraron un menor contenido de humedad y una mayor tasa de absorción de agua. Para la propiedad MOE paralelo, los paneles MLCC del árbol de caucho mostraron un valor medio más alto mientras que el MOR perpendicular de los paneles de bambú mostró un valor medio más alto. Para la resistencia al corte en la línea de cola, todos los tratamientos evaluados cumplieron con los requisitos normativos de EN-314-2: 1993. Entre las especies analizadas se recomienda el bambú, que ha mostrado un gran potencial para la fabricación de MLCC, además de representar una opción sostenible para el futuro.O objetivo desta pesquisa foi avaliar as propriedades físicas e mecânicas dos painéis de madeira laminada colada cruzada (MLCC) e bambu laminada colado cruzado (BLCC). Para a colagem das lâminas de madeiras (Eucalyptus grandis e Hevea brasiliensis) e bambu (Dendrocalamus giganteus) foi utilizado o adesivo à base de resorcinol-formaldeído (RF) com gramatura de 350 g.cm-2 por linha dupla de cola. As lâminas foram prensadas a frio sob pressão de 1MPa em temperatura ambiente durante o período de 24 horas. Foram adotados três tratamentos com base nas espécies: 1) lamelas de eucalipto; 2) lamelas de seringueira; 3) lamelas de bambu. Avaliou-se as propriedades densidade aparente, teor de umidade, absorção de água, flexão estática módulo de elasticidade (MOE) e módulo de ruptura (MOR) paralelo e perpendicular e resistência ao cisalhamento na linha de cola. Os resultados da análise química indicaram maior teor de extrativos e lignina para o eucalipto. O bambu foi o que apresentou maior densidade, diferindo-se significativamente das demais. Os painéis MLCC de seringueira evidenciaram menor teor de umidade e maior taxa de absorção de água. Para a propriedade MOE paralelo, os painéis MLCC de seringueira evidenciaram maior valor médio enquanto o MOR perpendicular dos painéis de bambu demonstraram maior valor médio. Para a resistência ao cisalhamento na linha de cola, todos os tratamentos avaliados atenderam aos requisitos normativos da EN-314-2 (1993). Dentre as espécies analisadas recomenda-se o bambu, que demonstrou grande potencial para a fabricação de MLCC além de representar uma opção sustentável para o futuro.Research, Society and Development2021-07-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1718110.33448/rsd-v10i8.17181Research, Society and Development; Vol. 10 No. 8; e33210817181Research, Society and Development; Vol. 10 Núm. 8; e33210817181Research, Society and Development; v. 10 n. 8; e332108171812525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/17181/15547Copyright (c) 2021 Hudson Venâncio Silva Garcia; Ana Carolina Corrêa Furtini ; Flávia Maria Silva Brito; Carolina Aparecida dos Santos; David Augusto Ribeiro; José Benedito Guimarães Júnior ; Lourival Marin Mendeshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGarcia, Hudson Venâncio SilvaFurtini , Ana Carolina CorrêaBrito, Flávia Maria Silva Santos, Carolina Aparecida dos Ribeiro, David Augusto Guimarães Júnior , José BeneditoMendes, Lourival Marin 2021-08-21T18:46:59Zoai:ojs.pkp.sfu.ca:article/17181Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:37:34.500579Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
