| Abstract Scope |
Studies have been carried out regarding the use of Natural Lignocellulosic Fibers (NLFs) as reinforcement in polymer matrix composites for ballistic application. The results were very promising and compared to Kevlar™ when used in a Multilayered Armor System (MAS). Although some different NLFs had been tested, studies about the ideal design of the composite yet to be done. This work aims to evaluate four designs of an epoxy matrix composite reinforced with piassava fibers, for MAS application. The ballistic tests were carried out in terms of Perforation and Backface Signature Test (P-BFS) and energy absorption as a stand-alone armor. In all conditions tested the P-BFS was lower than the limit of 44mm. Considering the stand-alone test the results showed that the energy absorption was statistically the same. But considering the integrity of the composite after the ballistic impact, both long and short fibers randomly distributed conditions had the best performance. |
