Abstract:
The development of new materials, which combine good mechanical properties, low cost and sustainability has become frequent. In this context, we highlight the development of composites that use natural fibers as reinforcement. These fibers are of great environmental importance because they are biodegradable, inexpensive and found in abundance in nature, as is the case of guaruman (Ischinosiphon koern), a species native to the Amazon region, and frequently found in floodplain regions of the state of Pará. Thus, this work aims to perform a mechanical characterization of polyester matrix composites reinforced by continuous and aligned guarumã fibers. The test specimens were produced in silicone molds meeting the specifications of ASTM D638, to perform tensile strength tests. From the values obtained after the tensile test, it was observed that the addition of the guaruman fibers to the polyester matrix increased the tensile strength value, and the incorporation of 30% by volume of fiber presented the best result. Thus, the polyester matrix composites reinforced with guaruman fibers, have a great potential, when compared to composites that have other natural fibers as reinforcement.
