| Abstract Scope |
Natural lignocellulosic fibers composites have been used in different applications, such as in the automotive industries, civil construction, sports equipment and packing. Among the natural lignocellulosic fibers (NLF), the hemp fiber has several applications and is historically used in textile industries, papers and even as medicine. However, only scarce applications of hemp fibers exist as engineering materials. Thus, the work investigated the impact resistance of epoxy matrix composites reinforced with hemp fabric, comparing different fractions of volumes of hemp fabric, 10, 20 and 30%, by Izod impact test. The results showed that although the 30% vol. hemp fabric composites samples did not break completely, their absorbed energy was substantially higher than the others composites. On the other hand, the 10 and 20% vol. composites showed similar performance on the test, which was corroborated by analysis of variance (ANOVA) and Tukey test. |
