Charpy Impact Tests in Epoxy Matrix Composites Reinforced with Continuous Sisal Fiber

Article Preview

Abstract:

The objective of this work was to investigate the toughness behavior of epoxy matrix composites reinforced with up to 30% in volume of long, continuous and aligned sisal fibers by means of Charpy impact tests. The addition of sisal fibers results in a visible improvement in the energy absorption ability of the composites. Macroscopic observation of the post-impacted specimens and the SEM fracture analysis showed that longitudinal rupture through the sisal fiber interface with the epoxy matrix is the main mechanism for the higher toughness attended by these composites.
