High strength and low weight materials are highly demanded in today’s automotive, aerospace, marine, medical, military, and agricultural equipment applications. Using composite materials is the best approach to increase high-strength and low-weight materials. This study focuses on evaluating the density, micro hardness, tensile, and wear behaviors of C355 aluminum alloy hybrid nanocomposites added in nanosized Graphene Oxide (GO) and Bio Silica (BS). These reinforcements are sourced from waste materials such as Thunder Coconut Shell (TCS) and Napier Grass (NG). The three different C355 aluminum alloy composites that have been improved by graphene oxide and bio-silica nanoparticles have been made utilizing the very traditional stir casting process. The percentage of GO and BS nanosized reinforcements is varied from 3wt.%, and 6wt.%. The cast composites density, hardness, and tensile strength are assessed. Unidirectional friction and wear tests are performed for each composition under six different loading conditions, ranging up to 60N, while maintaining a sliding speed of 5m/s. The worn surfaces and composite components underwent additional scrutiny through SEM analysis. By adding 6wt.% more GO/BS nanoreinforcement to the C355 Al alloy nanocomposite, the study’s findings show that the nanocomposite has almost 52.42% more tensile strength and 27.26% higher hardness than the basic alloy.
