Abstract Scope |
The natural lignocellulosic fibers have been gaining ground in engineering applications, especially in composites. In such a scenario, it is necessary to collect information from these materials in engineering applications. In this context, the present work aims to evaluate the ballistic properties presented by the epoxy composite of carnauba fibers (Copernicia prunifera). Plates of 15X12X1 cm3 were produced with 0 to 40% volume of carnauba fibers. The plates were tested with a 22 caliber (~3.3 g) in single projectile with a Gunpower SSS pressure rifle. In determining the impact velocity, an Air Chrony model MK3 ballistic chronograph was used. The implementation of fibers in the composite improved the dimensional stability and reduced the absorbed energy of the neat epoxy resin (112.7 J), where the composites with 40% showed lower results (63.8 J). The results obtained highlight the need for further study on the ballistic properties presented by these materials. |
