Izod impact tests in polyester matrix composites reinforced with fique fabric

Abstract

The fique fibers are studied worldwide as an alternative of synthetic fibers in composites. This study evaluated the impact resistance of this type of composite. Specimens were made with up to 30% in volume of fique fabric in an Izod normalized mold. The fique fabric was embedded with polyester resin and cured at room temperature for 24 h. The specimens were tested in Izod impact pendulum and the fracture surfaces were examined by scanning electron microscopy (SEM). The impact resistance of composites increased linearly with the relative amount of fique fabric reinforcing the composite. This performance was associated with the difficulty of rupture imposed by the fique fabric as well as the type of cracks resulting from the interaction jute fiber/polyester matrix that corroborate the energy absorption at the impact test.
