Experimental Investigations of Silicon Carbide - Fly Ash Reinforced Aluminium Metal Matrix Composite

Abstract

Metal matrix composites are used mostly in space ships, aerospace, automotive, nuclear bio technology, electronic and sporting goods industries, but due to their high cost, experiments are usually done to reduce the cost of composites and inexpensive materials are utilized for metal matrix composites. Fly Ash is one of the most inexpensive and low density reinforcement available in large quantities as solid waste by product during combustion of coal in thermal power plants. So, composites with Fly Ash can be used to reduce the cost of the metal matrix for applications in automotive and small engine applications. It is therefore expected that the incorporation of Fly Ash particles in Aluminium alloy will promote yet another use of this low cost waste by product and at the same time has the potential for conserving energy intensive Aluminium and thereby, reducing the cost of Aluminium products. In this investigation, 10% SiC particles reinforced Al-MMC was prepared using stir casting method. The ratio of Hardness with respect to the weight fraction on the specimen was prepared. The various mechanical test via hardness & tensile test are taken to analyze the properties .The microstructure of Al-MMC’s were studied in SEM microstructure.
