Theoretical reference: The composites are formed by combining two or more materials, enabling improvements in properties and a variety of applications. These materials are highlighted by presenting low cost and enabling environmentally friendly alternatives.
Method: Quantitative study, In this work, composites of polyester matrix reinforced by mauve fibers, jatoba wood residues and hybrid mauve/residue system, were analyzed mechanically and microstructurally. The fabrication of the composites began with the cut of the mauve fibers in the lengths of 5, 10 and 15 mm. In the manufacture of the specimens, terephthalic polyester resin was used with incorporation of fibers and residue. The specimens were produced in silicone molds, for the tensile strength tests and scanning electron microscopy (SEM) analysis.
Results and conclusion: From the results obtained in the tensile test, it is observed that the resistance of the composites with mauve fibers of 15 mm (25,09 MPa) and hybrids in the proportions of 75% fiber/25% residue (26,06 MPa). In the microstructural characterization, the composites analyzed presented factors that contributed to the improvement and reduction of performance in the results of tensile strength.
Implications of the research: It presents important and overwhelming results on composite materials with wood waste and mallow fibers, providing an alternative for inserting waste and fibers into materials with good properties and low cost.
Originality/value: The compounds stand out for their simple and viable manufacturing method, in addition to superior results in relation to proven properties. Given the need to search for new materials with good properties and with minimal impacts on the environment.
