In recent years, the results have been obtained with the use of waste and vegetable fibers, the dismemberment of the concept of a material can be called composite. A polyester resin composite (orthophthalic and terephthalic) composite and filler of wood produced in woodworking was obtained and studied. The processes of obtaining composites and a characterization of mechanical, thermal and physical properties in composite samples with a more specific fraction of 10, 20 and 30% were studied for three different granulometries, totaling six formulations for percentages. However, a formulation with 20% was chosen, because with that percentage already had a saturation of the mixture. The tests carried out for tensile, flexural, thermal, water absorption, density, biodegradation, environmental degradation and MEV tests. The composites obtained in all the studied formulations had lower mechanical resistance than the matrix, however it did not make it impossible to use them in applications where no significant efforts are required. In terms of thermal resistance or composite proposed to competitive with a resin matrix, having somewhat lower behavior. As expected the composites presented higher water absorption indices when compared to the polymer matrices. The apparent density of the composites does not present significant variation in relation to the used dimensions. It has been demonstrated, therefore, that the residues aggregated to the resin have a filling charge function. The composite was used for the manufacture of seat tops, demonstrating its feasibility of application in the fabrication of structures for low mechanical stresses.Acesso AbertoCompósitoResina poliésterResíduosFormulaçõesCaracterizaçãomasterThesisCNPQ::ENGENHARIAS::ENGENHARIA MECANICA
