Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Mechanical Design and Production Summary: This thesis studies the tribological behavior of dual matrix Al-CNT composites where the optimum values of significant parameters are determined to decrease the wear rate and increase hardness. The study considers the wear behavior as affected by the main control parameters; 1) wt.% CNT content in reinforcement particles (C), 2) the mixing ratio between reinforcement particles to soft aluminum matrix (M), 3) sliding speed (S), 4) applied load (L) and 5) covered distance (D). The study also considers the hardness affected by the main control parameters; 1) wt.% CNT content in reinforcement particles (C), 2) the mixing ratio between reinforcement particles to soft aluminum matrix (M). Response surface methodology including statistical design of experiments, modeling and optimization is applied. The optimized multi objective model and the validating experiments show that optimal levels at minimum wear and maximum hardness can be reached at about (C) 5%, (M) 56%, (D) 0.6km, (L) 8N, and (S) 0.8m/s
