Abstract:
Increasing awareness around the world of the urgent need to reduce the use of non-degradable synthetic materials, and the problem of disposing of personal protective vest and helmet have driven research into new more environmentally sustainable materials for ballistic applications. In this context, natural lignocellulosic fibers can be promising options because they are non-polluting and have specific mechanical properties comparable to those of commonly used synthetic fibers, in addition to being significantly cheaper. Thus, in order to evaluate the hybridization of curaua fibers (Ananas Erectifolius) with aramid fibers in epoxy composites for ballistic helmets, 3-points flexural tests were performed. From the obtained results, it can be inferred that the hybridization was negative as it didn’t produce a real gain for the flexural properties of the epoxy/curaua composite. On the other hand, the results of this composite were relevant and promising
