Composite materials are one of the most interesting groups of materials currently used, as they have numerous advantages over conventional materials. Reinforcement is the discontinuous component of the material, and, in general, presents the greatest strength in composites. In clay-reinforced composites, the mechanical properties can be improved and facilitate the processability of the manufactured product. The objective of the work is based on manufacturing and analyzing polymeric composites made with clay using a polymeric matrix, in addition to physically and mechanically characterizing them and studying their flame retardancy. Composite materials of isophthalic polyester matrix were made, using clay as particulate material. The hand lay up method was adopted for their manufacture. In the resin was added 1,5 % (v/v) of cobalt accelerator and 1 % (v/v) of initiator and the proportions of clay were: 0 %, 5 %, 10 %, 15 %, 20 % and 25 %. The specimens were submitted to physical tests of apparent specific mass, apparent porosity and water absorption according to ASTM D792, ASTM D2734 and ASTM D570, respectively. In addition to the tensile and bending tests that followed the ASTM D3039 and ASTM D790 standards, respectively. And finally, the flame resistance test following the ASTM D635 standard. Regarding the physical tests, all compositions had similar averages and all increased in relation to the matrix. Mechanically, the results were favorable where the addition of clay affected positively under tensile stresses, where the best result was given with 21,25 MPa with 20 % of Icoaraci clay and bending, where the best result was given with 68,53 MPa with 15 % Icoaraci clay compared to the full matrix. For the flammability test, there was not such a significant decrease in the burning rate, with the lowest rate being 20,12 mm/min with 15 % of Icoaraci clay, however the results remained lower than required by the ASTM D635 and CONTRAN.Acesso AbertoCompósitosProcessamentoPoliésterArgilaPropriedadesCompositesProcessingPolyesterClayPropertiesCNPQ::ENGENHARIAS::ENGENHARIA DE MATERIAIS E METALURGICA::METALURGIA DE TRANSFORMACAO::TRATAMENTO TERMICOS, MECANICOS E QUIMICOSTrabalho de Curso - Graduação - Monografia
