| Abstract Scope |
The increasing awareness around the world of the urgent need to reduce the use of non-degradable synthetic materials, and the disposing problem of ballistic vests and helmets have driven research into new, more socio-environmentally sustainable materials for ballistic application. In this context, natural lignocellulosic fibers (LNFs) can be promising options because they are socio and ecofriendily and have specific mechanical properties comparable to commonly used synthetic fibers, besides to being significantly cheaper. For applications under high strain rate compression loadings as ballistic impact, the material response varies significantly as compared to static loading. Thus, as the objective of evaluating the hybridization of curaua fibers (Ananas Erectifolius) with aramid fibers in epoxy composites for ballistic helmets, dynamic compression tests with split Hopkinson pressure bar (SHPB), under about 1400s<sup>-1</sup> deformation rates, were performed. Dynamic stress-strain plot was obtained for each composite from which mechanical properties at high strain rates are extracted. |
