| Abstract Scope |
Natural lignocellulosic fibers have been increasingly studied since attentions were drew by environmental problems. Among several applications, a few studies evaluated this material in ballistic protection in a multilayered armor system. This interest comes from the availability, low cost, and mechanical features that could be compared to synthetic fibers. Among the natural fibers, the hemp has been historically explored in several applications. Thus, this paper aims to evaluate the performance of epoxy matrix reinforced with hemp fabric on the ballistic test using a .22 ammunition. The composites were reinforced with 10, 20 and 30 vol% of hemp fabric and tested as stand-alone target to evaluate the absorbed energy. Through statistical analysis, it was possible to compare the results of the tests, which indicated no significant difference between the samples. Although, the 30 vol% fabric composites presented more reliability and homogeneity on the results and integrity of the specimens. |
