In this study, the effects of hybridization of basalt fibers and Kevlar, combined with the incorporation of graphene nanoplatelets (GnPs), on performance under low-velocity impacts were experimentally investigated. Two different hybrid structural compositions, reinforced with basalt and Kevlar composite materials, were fabricated using a hand-casting technique followed by vacuum bag molding, with variations including and excluding graphene sheets. The synergistic effects of hybridization, along with the modification of graphene nanosheets on the impact properties of basalt/Kevlar hybrid composites, were analyzed under an impact energy of 30 J, with varying graphene nanosheet loading. The observed optimum improvement in the peak load and absorbed energy of the samples was recorded at 9.4% and 45.7%, respectively, when Kevlar fibers were placed in the outer layers. Conversely, the samples showed 13.35% and 20.36% improvements in the peak load and absorbed energy when basalt fibers were placed in the outer layers. The superior impact properties of the hybrid structures are attributed to the strong interfacial interactions between the fibers, epoxy, and GnP nanoparticles, which facilitated a significant performance improvement and optimal stress transfer from the fibers and nanoparticles to the matrix.
