Thus, the probability of the physical space being saturated is great, so possible accidents or even improper disposal are considered. Aiming mainly at the environmental issue and applicability for this material, this work produced composite materials of isophthalic polyester matrix with industrial wastes (red mud, kaolin and copper) with a particle size of less than 100 mesh and with the purpose of increasing the mechanical resistance. 5 % of blanket-shaped metal fiber. The composites were made according to the hand lay-up method. The matrix used was isophthalic polyester resin, using activator (1.5 % v/v) and initiator (1.0 % v/v). Waste characterization was performed by X-ray diffraction and metallic fibers by Dispersive Energy Spectroscopy - EDS. The specimens were subjected to the physical tests of Water Absorption, Apparent Specific Mass and Apparent Porosity (NBR 12766), flammability (ASTM D 635), flexure (ASTM D 790) and tensile (ASTM D 3039) mechanical tests. The fractured surface of some samples from the tensile test by scanning electron microscopy - SEM. The results showed increase in physical properties according to increase of waste. The composites presented flame retardancy, the LV 20 % FM 5 % composite presented better performance with propagation rate of 14.99 mm/min. The FM 5 % composite showed higher flexure strength (115.92 MPa) followed by the CO 5 % FM 5 % hybrid composite (106.53 MPa). The LV 5 % FM 5 % composite achieved higher average tensile strength (38.5 MPa). The results showed that there was an increase in the tensile strength limit of metal fiber composites in relation to the full matrix. The morphological analyzes of the fracture surfaces were efficient to determine the failure mechanisms and characteristics present in the materials, where the phenomena of fibers arranged transversely in the direction of loading, ruptured fibers and fiber distribution and wastes were observed. Thus, from the characterization of the composites performed, demonstrated the feasibility of making them for future applications as wall partitions, for example, however, there is a need for other types of characterizations to make a greater measurement of the properties of the composite.Acesso AbertoMateriaisFibrasResíduoPolímerosMaterialsFibersWastePolymersCNPQ::ENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICA::MATERIAIS NAO METALICOS::EXTRACAO E TRANSFORMACAO DE MATERIAISTrabalho de Curso - Graduação - Monografia
