However, few Brazilian species are currently used in the production of Cross Laminated Timber. The aim of this work was to characterize the bonding quality of four Brazilian reforestation species (Pinus elliottii (pino ellioti), Eucalyptus grandis (eucalipto), Toona ciliata (toona) and Acrocarpus fraxinifolius (lazcar)) in the manufacture of Cross Laminated Timber with two-component polyurethane adhesive and five different pressure levels (from 0,1 MPa to 1,3 MPa). Bonding quality was evaluated through delamination and glue line shear tests based on the European standard. Delamination was affected by the wood species, and the best adhesion occurred for the Cross Laminated Timber manufactured with Pinus elliottii (pino ellioti) and Acrocarpus fraxinifolius (lazcar) at the bonding pressure of 0,7 MPa. Cross Laminated Timber bonding pressure did not affect the percentage of wood in the shear test fractured surface, whereas higher density Cross Laminated Timber showed higher percentages. 2024 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48578772002 https://www.redalyc.org/journal/485/48578772002/ https://www.redalyc.org/journal/485/48578772002/html/ https://www.redalyc.org/journal/485/48578772002/48578772002.epub https://www.redalyc.org/journal/485/48578772002/movil 10.4067/s0718-221x2024000100402 en http://www.redalyc.org/revista.oa?id=485 Maderas.
