An Investigation on Effect of Inorganic Reinforcement Materials and Taguchi-Based Optimization on Manufacturing of Hybrid Composites (AI7068)

Abstract

<div class="section abstract"><div class="htmlview paragraph">A crucial characteristic of composites, which are manufactured from elements of metal, is their mechanical and durability properties. A variety of reinforcing agents and metal nanoparticles are used to create aluminum-based hybrid metal-material composites. These composites are an advantageous alternative for sectors with limited resources because of their robustness, wear resistance, and thermal management capabilities. Manufacturing sectors employ Taguchi optimisation and Grey relational analysis to enhance the mechanical and durability properties of aluminum-based hybrid metal composites. To comprehend the interrelationships between reinforcing materials such as Al₂O₃ and SiC at constant fly ash concentration, five responses such as wear loss, tensile strength, elongation rate, impact strength, and hardness were considered and assessed. The Grey Relational Analysis (GRA) method is used to optimise these responses and transform them into Grey Relational Grade (GRG). The Grey Relational Grade (GRG) Analysis of Variance (ANOVA) results were supplemented by a regression-based ANOVA analysis. SiC (p value - 0.024) and Al₂O₃ (p value - 0.029) have been demonstrated to be statistically significant in this situation. It was determined that the correlation coefficient (R²), adjusted correlation coefficient (Adj R²), Fischer's value (F-value), and probability value (p-value for the probabilistic variables were found to be 81.43%, 70.29%, 7.31, and 0.028, respectively. All of the results have been deemed satisfactory and fall within the recommended ranges. However, to confirm the model's fit, a validation experimental run based on run 06 conditions (A₁B₁C₁) was performed. The experimental grade that was predicted turned out to be 0.971. It was concluded that engineers can fabricate an incredibly low combination of reinforcement materials and applied load, Taguchi optimisation produces robust composite with minimal wear loss, elongation rate, greater hardness, and tensile strength.</div></div>
