Item Materiais compósitos de matriz poliéster reforçados com resíduos de madeira de diferentes morfologias(INSTITUTO DE TECNOLOGIA, 2013) LOPES, Carlos Eduardo Pinto; PEREIRA, Léo César de Oliveira; COSTA, Deibson Silva da; LOPES, Raimundo Valdan Pereira; PINTO, Vagner Barroso; LEITE, Jandecy Cabral; FUJIYAMA, Roberto Tetsuo; MAGALHÃES, Edilson MarquesThis study presents the production and characterization of polyester matrix composites reinforced with residues from the Amazon timber industry. Using Angelim Pedra wood powder in different particle sizes and weight fractions (6.86% and 10.86%), the composites were evaluated for their mechanical properties through tensile tests. The results showed that smaller particles increase tensile strength, indicating that the reuse of these residues is viable and contributes to industrial sustainability.Item Avaliação da Variação das Frações Mássicas das Fibras nas Propriedades Mecânicas do Compósito Poliéster Reforçado por Fibras de Sisal(Instituto de Tecnologia, 2013) EL BANNA, Wassim R.; COSTA, Delbson S. da; GILDO, Camila C. R.; LOPES, Raimundo Valdan P.; PINTO, Wagner B.; LEITE, Jandecy Cabral; FUJIYAMA, Roberto T.; QUARESMA, João Nazareno NonatoThe study evaluated the influence of sisal fiber mass fractions (1.41% to 9.41%) on the mechanical properties of polyester matrix composites. Specimens were fabricated by manual molding and subjected to tensile tests according to ASTM D 638. Results showed that the 5.41% mass fraction achieved the highest tensile strength (22.23 MPa), outperforming other natural fibers. Beyond this fraction, strength decreased due to fiber-matrix interface saturation. The manufacturing method proved viable for producing sustainable and low-cost materials.
