Synthesis Characterization and Mechanical Behavior of Rice Husk Ash Reinforced Al-20mg 10 Cu Alloy Matrix Hybrid Composites

The aim of this work is to fabricate hybrid composites by using Rice husk ash (RHA), an agro waste as reinforcement to AL-20MG-10CU high strength alloy. Rice husk ash particles of 3, 6, 9 & 12 % by weight were used, to develop metal matrix composites, using a liquid metallurgy route. The microscopic structural studies have been carried out using scanning electron microscope, to analyze the distribution of RHA particles. The usage of any metal matrix composites always depends upon the strong wettability of reinforcement particles in a matrix. For the strong wettability, uniform distribution of particles and good disposability stir casting method is considered, for the development of composites. The physical and mechanical behavior of the material was determined through density, hardness, tensile strength, impact energy calculations. The results revealed that, abundant rice husk can be used in the production of metal matrix composites for engineering applications.
