Graphene nanoplatelets inclusion effects on mechanical properties of the hybrid kevlar/basalt fiber reinforced epoxy composites

This study experimentally examined the effects of hybridizing Basalt and Kevlar fi bers on the tensile, and fl exural performance of composite materials with the inclusion of Graphene nanoplatelets ( GnPs ) . Various hybrid composites were fabricated, incorporating Basalt and Kevlar fi ber composites with 1, 3, and 5 wt% of GnPs as well as without GnPs, as well as hybrid composites featuring different weight content of GnPs reinforcing with with Basalt and Kevlar fi bers. The fi ndings of this study indicated that the mechanical properties of epoxy resin were significantly enhanced through the synergistic effects of hybridization with basalt and Kevlar fi bers, as well as the incorporation of graphene nanoplatelets ( GnPs ) . The significant increasing in mechanical properties was attributed to the strong interfacial interactions between the epoxy matrix and GnPs nanoparticles, which facilitate improved stress transfer from the fi bers and nanoparticles to the matrix. This enhanced stress transfer capability accounts for the superior resistance to fi ber pullout observed in composites reinforced with GnPs compared to those without nanoparticles.
