In this work, a model was developed using Taguchi technique to study the factors influencing the fatigue life of aluminium matrix composite. Aluminium 6061 is reinforced with varying load, weight percentage Al2O3 particles and particle sizes. Stir casting method is used to prepare the specimens. Experiments were conducted for pure reverse bending by RR Moore method. The effect of applied load, weight fraction (%) and sizes of the particles on the fatigue life was investigated. It is observed that as applied load and weight fraction increases, fatigue life is decreasing. The larger particle size and less weight fraction is have positive effect on the endurance of the specimen. The optimum values of the life cycle is observed at 120 microns particle size, 5 kg load with 5% weight fraction. The forecast model indicates that the significant parameter that impacts the fatigue life was particle size, followed by applied load and weight percentage of reinforcement. Confirmation test reveals that, the model results were observed to be near to the experimental values.
