With the society’s demand for new environmentally friendly materials, new alternatives, such as the PALF fiber, are being developed to replace synthetic fibers which are harmful to the environment. However, there is limited information about the impact resistance of polyester composites incorporated with PALF fibers. Therefore, the aim of this work was to analyze the absorbed impact energy of these composites. Impact specimens with up 30% in volume of PALF fibers were fabricated. The fibers were press molded with a orthophtalic polyester resin mixed with the proper hardener and set to cure for 24 hours at room temperature and pressured in the mold up to 5 tons. Specimens were test in a charpy pendulum. The results showed increase in the absorbed impact energy with higher amount of incorporated fiber. This performance can be explained by the difficult of rupture imposed the type of cracks resulting from fiber/matrix interaction.
