Multilayered Armor Systems (MASs) are intended for personal protection against high-impact energy ammunition promoting light and effective protection. Synthetic fiber material as KevlarTM is commonly used as second layer of the MAS. However, composites reinforced with natural fibers have been considered as an alternative because of their singular characteristics such as low cost, biodegradability and mechanical properties comparable to synthetic fibers used as reinforcement. Thus, this year, at the symposium of Characterization of Minerals, Metals and Materials, 8 works will be presented focusing on the ballistic performance of different natural fiber-based composites applied to MASs for personal protection. The results revealed that all investigated composites reinforced with different natural fibers, including curaua, PALF, jute, mallow, and fique fibers, disclosed similar ballistic performance of KevlarTM as MAS second layer. This unexpected performance was explained as a consequence of fragment capture mechanisms, which was the same observed for the MAS with KevlarTM.
