Experimental Investigation of Mechanical and Wear Properties of AL7075/Al2O3/MICA Hybrid Composite

Composite materials are the recent advancement technique in the feld of material science. A composite material gives a
unique property that is never shown from the particular alloy material. The dispersion of Reinforcement particles with the matrix material changes its mechanical and tribological properties. Because of its lightweight and high strength, Aluminum Metal Matrix Composite AMMC is used in many felds. Depends upon the Reinforcement particles, matrix property can change. Aluminum 7075 is the durable alloy used in the aerospace and automotive industries. In this present investigation, Al 7075 is dispersed with Alumina (Al2O3) and Mica by the stir casting process. And the samples are characterized by various mechanical tests like Hardness test and Impact test and studied using a scanning electron microscope. From the report, the mechanical properties of Al 70775 compositions are improved compared to the non-reinforced base material.
