Abstract
This work investigated the toughness behavior of polyester matrix composites reinforced with up to 30% in volume of long, continuous and aligned fibers extracted from the eucalyptus wood by means of Charpy impact tests. It was found that the addition of eucalyptus fibers results in a marked increase in the absorbed impact energy of the composites. Macroscopic observation of the post-impact specimens and SEM fracture analysis showed that longitudinal rupture through the Eucalyptus fiber interface with the polyester matrix is the main mechanism for the remarkable toughness of these composites.
