The leaf spring is one of the vital components of an automobile which absorbs vibration from shocks generated due to uneven road surface. It is made up of conventional materials like plain carbon steel are heavy and add weight to vehicle which reduces mileage. This necessitates new material which is light in weight and could provide adequate strength to leaf spring along with higher strain energy absorption to absorb shocks.The current research investigates the application of Graphite Aluminum MMC on leaf spring for mass reduction using Finite Element Method.  The CAD model is developed in ANSYS design modeler and analyzed in workbench.  The design is then optimized using Taguchi Response Surface method using Central Composite Design scheme. The RSM optimization generated specific set values for optimization variables (inner radius and outer radius) along with sensitivity plot and goodness of fit curve. The application of Graphite Aluminum MMC resulted in 56.1% of mass reduction without increase in stress as compared to conventional steel material.
