摘要

In the present work, chemical modification of the sugarcane bagasse fibers by estherification through anhydride system was studied to use as reinforcement in polyester matrix. Sugarcane bagasse fibers were estherified during 5 hours with acetic anhydride, toluene, acetic acid and percloric acid. The modification the fibers were evaluated by techniques scanning electron microscope (SEM) and X-ray diffractometry (XRD). Furthermore, fibers were mixed with the polyester resin and compression molding, in which fibers were responsible for 5 wt% in the composition. After that, the composite was left to cure at room temperature for 24 hours and machined into specimens of according to ASTM D-3039 specification. Tensile tests were carried out using EMIC machine according to ASTM D3039. Results relieved that composites presented better mechanical strength when compared to pure polymer, which exhibited an increase de 71.5% compared to the pure polymer.
