Caracterização mecânica de compósitos de matriz polimérica reforçados com resíduo sólido “pó do balão” com e sem fibra do caroço do açaí

Abstract

The adequate destination of residues, generally is one of the largest challenges of the industry today. In the steel industry, about 74% of solid waste "powder flask" deposited in improper locations, resulting in severe environmental problems, with which the industry must deal with. Moreover, in the food industry, tons of waste arising from açaí process are generated annually endless conducive. Different methods have been studied for the use of such waste. Accordingly, this work had as objective develop and mechanical characterization of composites with unsaturated polyester resin as matrix, reinforced by "powder flask" and hybrid composites reinforced with the siderurgical residue and fiber of mesocarp of the lump of açaí, and for both types, samples of 15g, 20g, 25g and 30g of powder and, for hybrids, fixed amount of 20g of fiber. Results indicate that siderurgical residue has potential performance as a reinforcement in the resin employed, and for hybrids, improvements in the mechanical properties were not observed.
