Abstract:
Environmental concerns have become increasingly frequent, driving the development of alternative materials that use renewable resources. In this context, the composite materials of polymeric matrix with the use of vegetable fibers as reinforcement stand out. Vegetable fibers stand out for their abundance in nature, low cost, besides presenting satisfactory results when compared to synthetic fibers. Thus, it is possible to highlight the Guarumã (Ischnosiphon arouma), an abundant species of the Amazon region and widely used in the making of basketry handicrafts. Thus, this work aims to produce composites of polyester matrix, using Guarumã fibers as reinforcement. The process of making the composites began with the analysis of the fibers, the specimens were produced individually in a silicone mold with the incorporation of 10, 20 and 30% in volume of fibers. The tensile mechanical properties of the composites were evaluated according to ASTM D 638 guidelines. The results obtained revealed that the incorporation of Guaruma fibers in polyester matrix did not significantly change the values obtained in relation to pure resin, however, the Guaruma fiber shows great potential as reinforcement in composite materials
