Abstract Scope |
The titica vine fibers (Heteropsis flexuosa) demonstrated great potential for use as a reinforcing fiber in polymeric matrix composites. In the present study, were manufactured composites with titica vine fibers, through the compression molding process, in the volumetric fractions up to 40% v/v of fibers, the purpose was to investigate the average charpy impact energies. For composites with 40% v/v of fibers, there was the most efficient performance of the reinforcement, with the predominance of failure mechanisms such as fiber rupture and interfacial detachment, which were possible to be observed from the fractographic analysis, obtained by SEM. The Tukey test confirmed that composites with 40% v/v of fibers performed better, increasing energy absorption from 61.52 J/m to 75.05 J/m. However, it was also found that the fibers acted as weakening agent in composites of 20% v/v of fibers when compared to the control group (pure epoxy). |
