    Aplicação de madeiras amazônicas em elementos de madeira lamelada colada (MLC)
    (Universidade Federal do Pará, 2023-03-16) NEVES, Paulo Henrique Lobo; MOUTINHO, Victor Hugo Pereira; http://lattes.cnpq.br/8464600937488553; MACEDO, Alcebíades Negrão; http://lattes.cnpq.br/8313864897400179
    Timber is considered on the world stage as the primary building material of the 21st century. However, for this potential to be actualized, technologies for unfolding and using the raw material, such as Glued Laminated Timber (glulam), need to be disseminated and used in a wider range of species. In this regard, we emphasize that, despite the great existing diversity, only some studies are found to verify the potential use of Amazonian timber in glulam. This way, this paper aims to analyze the gluing of ten species native to the Amazon, namely: Jacaranda sp., Simarouba amara Aubl., Astronomium lecointei, Couratari sp., Cedrela fissilis., Cordia Goeldiana Huber, Hymenaea courbaril., Dipteryx odorata. Euxylophora paraensis., Mezilaurus itauba., and the combination with four different types of adhesives, two structural resistant to moisture and two non-structural, using a shear sample of solid timber as a evidence, with a minimum of 20 repetitions per treatment. Complementary tests such as delamination and static bending were carried out. We verified that for some species there was an adhesive with statistically equal and superior resistance in some combinations compared to the control sample, demonstrating that the studied species have the potential for the production of glulam, as well as for other products that use adhesives.
