Optimization on the Mechanical Properties of Aluminium 8079 Composite Materials Reinforced with PSA

Abstract

AA 8079 with variable percentages of peanut shell ash (PSA) was created by stir casting (2.5 percent, 5 percent, 7.5 percent, 10 percent, 12.5 percent, and 15 percent). Compared some of the physical and mechanical properties of the composite material were to the alloy matrix alloy (density; porosity percentage; hardness; wear index; tensile strength; and impact strength). Peanut shell ash reinforcements were found to be distributed uniformly throughout the Aluminum Matrix, with pockets of agglomerated reinforcement particles. The hardness, wear index, and density of the composite were enhanced by adding PSA particles. Compared to the matrix alloy without reinforcement, the composites had lower tensile and impact strengths. Mixture design with Design-Expert (Stat EASY) software package indicated the appropriate matrix and reinforcing combination proportions and how they influenced composites’ studied properties. Composites’ physical and mechanical properties were predicted and optimized using regression models created and the ideal mixture of matrix and reinforcement wt. According to optimization findings, the components for optimal composite characteristics’ responses are 93.48 and 6.52 percent of matrix and reinforcement wt% particles. They can utilize PSA-reinforced AA8079 core materials to make automotive components that need lighter, stackable, and wear-resistant.
