Abstract:
In the last decades, the search for materials that present high mechanical performance and are in accordance with sustainability guidelines has become increasing. The use of natural fibers in the production of new materials has been gaining prominence among researchers, due to the fact that some fibers have high mechanical performance and good thermal stability, two highly attractive properties in composite materials. In this scenario, the use of tururi fabric as a reinforcement agent in composites of polymeric matrix emerges as a viable alternative for sustainable disposal of this waste coming from the harvesting stage of its fruits. Thus, the present study aims to evaluate the mechanical behavior of the composites tested in traction. The composites were produced by hand lay-up method using percentages of 2.5, 5.0 and 7.5% by mass of tururi fabric reinforcement. The mechanical characterization revealed that when submitted to traction the composites with 2.5% reinforcement presented the best mechanical performance, reaching 30 MPa and 0.97 tensile strength and modulus of elasticity, respectively. The micrographs of the fracture region revealed structural defects originating from the composites manufacturing stage. The results indicate that the fabric acted as a reinforcement agent in a percentage of up to 2.5% of reinforcement.
