Abstract: Composites involve two or more component materials that are generally combined in an attempt to improve material properties such as stiffness, strength, toughness. Composed of a discrete reinforcement & distributed in a continuous phase of matrix, composites are the most successful materials used for recent works in the industry. There has been an increasing interest in composites containing low density and low cost reinforcement. Among various reinforced materials used, fly ash is one of the most inexpensive and low density reinforcement available in large quantities as waste product during combustion of coal in thermal plant. In this paper AL- fly ash composites produced by fly ash were observed with the help of optical microscopy. The hardness, tensile, toughness tests were carried on the composite. Physical and mechanical properties of composite were obtained.
Keywords: Composite material, fly ash, metal matrix composites, stir casting.
