In the present study, the effects of hybridization of Basalt and Kevlar fibers in conjunction with the incorporation of Graphene nanoplatelets (GnPs) on the performance under low-velocity impact were experimentally examined. Two different hybrid structural configurations, reinforced with Basalt and Kevlar composites, were fabricated utilizing a hand lay-up technique followed by vacuum bag molding, with variations that included and excluded GnPs. The synergistic effects of hybridization coupled with the modification by GnPs on the impact characteristics of the Basalt/Kevlar hybrid composites were analyzed under an impact energy of 30 J while varying the GnPs loading. The optimal enhancement observed in the peak load and absorbed energy of the specimens was recorded as a 9.4 % and 45.7 % improvement, respectively, when Kevlar fibers were positioned in the outer layers; conversely, the specimens demonstrated enhancements of 13.35 % and 20.36 % in peak load and absorbed energy with the incorporation of 1 wt% and 3 wt% GnPs when Basalt fibers were situated in the outer layers. The increase of the impact properties of the hybrid structures was ascribed to the robust interfacial interactions established among the fibers, epoxy, and GnPs nanoparticles, which facilitated a notable enhancement in performance and optimal stress transfer from the fibers and nanoparticles to the matrix.
