Ballistic impacts impose instantaneous and non-uniform loads, resulting in localized fractures in target materials. In recent years, polymer matrix composites reinforced with natural fibers in laminated configurations—combined with synthetic fibers, for example—have gained prominence as sustainable alternatives for ballistic protection applications. This review analyzes how fiber type, orientation, and hybridization strategies influence the dynamic impact resistance of these materials. Since ballistic performance is strongly related to fiber behavior, proper arrangement is essential for efficient energy dissipation. The literature identifies several failure mechanisms under high strain-rate conditions, including fiber breakage, matrix cracking, pull-out, fiber bridging, and delamination. Hybridization with other fibers shows potential to enhance performance by combining complementary mechanical properties. However, the complexity and simultaneous occurrence of damage mechanisms make analytical modeling a challenge. This review highlights the current challenges, advances, and research gaps in the study of these composites. |
