This study investigates the impact of porosity on mechanical properties aluminum matrix composites reinforced with ceramic particles, focusing optimization volume fraction and to enhance tensile strength. Using Finite Element Analysis (FEA) Variance (ANOVA), effects varying fractions (5%, 10%, 15%, 20%, 25%) levels (1%, 2%, 3%, 4%, 5%) Von Mises stresses were systematically analyzed. The results demonstrated that as increased, stress also while higher contributed better distribution enhanced properties. Optimization analysis identified optimal parameters a 25%, level 1.01%, particle size 30.083 µm, pore diameter 9.020 achieving desirability score 0.895 9.06E-08 N/µm2. ANOVA confirmed statistical significance these parameters, P-value threshold <0.05. These insights are crucial for understanding how optimize reinforcement in composite materials, providing valuable guidance applications aerospace automotive industries, where lightweight high-strength materials vital.
