Resumo: The production of wooden panels in Brazil is predominantly carried out with wood from planted forests, mainly from the Pinus and Eucalyptus genera. Currently, research is being carried out with wood panels for the development and characterization of new products, different from those traditionally found on the market and which include the use of wood, in its different forms, in the same product. Therefore, this study was carried out to evaluate the physical and mechanical properties of hybrid panels produced with particles and veneers of Pinus taeda wood in different compositions and reinforced with carbon fiber. Four types of panels were produced in different compositions of blades and particles that were evaluated with and without carbon fiber reinforcement. Urea-formaldehyde resin was used for bonding the particles and blades for manufacturing the hybrid panels, and low viscosity epoxy resin for bonding and impregnating the carbon fiber blanket on the hybrid panel faces. It was verified that the panels produced with the addition of veneers presented greater resistance in the mechanical tests, except for the internal connection property. The panels produced with the addition of two veneers showed better mechanical properties compared to the other panels in this study. The properties of swelling in thickness, modulus of rupture and modulus of elasticity in perpendicular static bending tests were impaired by the use of blades on the panel faces. The addition of carbon fiber considerably increased the properties of modulus of rupture and modulus of elasticity both in the parallel and perpendicular directions, reaching values 50% higher than the panels without carbon fiber, however, it did not influence the bonding properties internal and screw pullout.

Atualmente, pesquisas vêm sendo realizadas com painéis de madeira para desenvolvimento e caracterização de novos produtos, diferentes dos tradicionalmente encontrados no mercado e que incluem a utilização da madeira, em suas diferentes formas, num mesmo produto. Diante disso, este estudo foi conduzido visando avaliar as propriedades físicas e mecânicas dos painéis híbridos produzidos com partículas e lâminas de madeira de Pinus taeda em diferentes composições e reforçados com a fibra de carbono. Foram produzidos quatro tipos de painéis em diferentes composições de lâminas e partículas que foram avaliados com e sem o reforço de fibra de carbono. Utilizou-se resina uréia-formaldeído para colagem das partículas e lâminas para a fabricação dos painéis híbridos, e resina epóxi de baixa viscosidade para a colagem e impregnação da manta de fibra de carbono nas faces do painel híbrido. Verificou-se que os painéis produzidos com a adição de lâminas apresentaram maior resistência nos ensaios mecânicos, exceto para a propriedade de ligação interna. Os painéis produzidos com a adição de duas lâminas, apresentaram melhores propriedades mecânicas em comparação com os demais painéis desse estudo. As propriedades de inchamento em espessura, módulo de ruptura e módulo de elasticidade em ensaio de flexão estática perpendicular foram prejudicadas pelo uso de lâminas nas faces do painel. A adição da fibra de carbono aumentou consideravelmente as propriedades de módulo de ruptura e módulo de elasticidade tanto nos sentidos paralelos e perpendicular, chegando a apresentar valores 50% superiores, aos painéis sem a fibra de carbono, no entanto, não influenciou as propriedades de ligação interna e arrancamento de parafuso.Submitted by Fabiano Jucá (fjuca@unicentro.br) on 2023-06-29T18:49:52Z No. of bitstreams: 1 Dissertação - Erick Chagas Mustefaga.pdf: 1250856 bytes, checksum: e5200fcfbde5e3fc49999cfe7ed61396 (MD5)Made available in DSpace on 2023-06-29T18:49:52Z (GMT).
