The replacement of synthetic fibers to natural fibers has been the subject of intense research, particularly when applied in composites. In this work, the tucum fibers (Bactris setosa), typical of the Amazon Region, were investigated as reinforcement of the epoxy polymer matrix. The composites prepared with different volume fractions (20 and 40%) of tucum fiber were characterized for Izod impact and ballistic impact energy absorption by .22 ammunition. The results showed that the composite with 40% of tucum fiber presented an increase of 86% in the average absorption of Izod impact energy in relation to the composite with 20% vol of tucum, however, it exhibited worse ballistic performance.
