Mechanical and wear behaviour of flyash reinforced epoxy composites

Abstract

In this research, a flyash/epoxy composite was fabricated using conventional hand layup method. The mechanical and tribological behaviour of composite was investigated by changing the volume of flyash to 5, 10 and 15% vol. The mechanical properties such as compression strength, hardness, impact strength and tensile strengths were determined as per ASTM standards. Results reveal that the mechanical properties, such as density, tensile strength and the compression strength increased as the amount of flyash increased up to a critical point, decreased with further increment in percentage of flyash. Tribological results reveal that, when the percentage of flyash is increased there is a significant decrease in wear volume loss. The minimum wear loss is observed at the optimum values for loads 15N, speed 300rpm and distance is 300m.
