Avaliação da Variação das Frações Mássicas das Fibras nas Propriedades Mecânicas do Compósito Poliéster Reforçado por Fibras de Sisal. In: 12° Congresso Brasileiro de Polímeros (12°CBPol), 2013. Anais... [S.l.], 2013.https://rigalileo.itegam.org.br/handle/123456789/1018The 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.pdf.Materiais CompósitosFibras de SisalResistência à TraçãoPoliésterSustentabilidadeDissertação de MestradoEngenharia de Materiais e Metalúrgica
