Investigation of ballistic and mechanical properties of AlNPB metal matrix composites reinforced with TiCN decorated graphene nano flakes for light armored vehicles

Abstract

In response to evolving military strategies and technology advancements, this study investigates the ballistic and mechanical properties of novel defense grade Aluminium Nickel Phosphorized Bronze (AlNPB) Metal Matrix Composites (MMCs) reinforced with 2, 4, and 6 wt% of Titanium Carbonitride (TiCN) decorated graphene nanoflakes (TG NPs). The TG NPs were synthesized via modified Hummer's method, mechanically milled with TiCN, and integrated into the AlNPB matrix through the stir casting technique. The fabricated MMCs were characterized using XRD, FTIR, and SEM analyses to evaluate the formation of the nanocomposite and MMC. A series of mechanical tests, including tensile, impact, and compression analyses, identified 4 wt% as the optimum filler loading to enhance mechanical strength. The corrosion resistance of the MMCs was studied alongside their morphological analysis. Explicit ballistic tests yielded satisfactory results, bolstering the potential of the fabricated MMCs for use in Light Armored Vehicles (LAVs). This research contributes a valuable MMC candidate for enhancing the performance and durability of LAVs in challenging environments.
