Abstract

In this study, aluminium LM24 hybrid composites were fabricated by reinforcing eco-friendly rice husk ash and Titanium oxide powder. The casting method was adopted is stir casting process method. Titanium oxide and rice husk ash were added in different ratios in percentage by weight. The ratios of these are 2:1, 2:3, 2:5, 4:1, 4:3, 4:5, 6:1, 6:3 and 6:5 defined for study purpose. The behaviour of aluminium LM24 against these weight ratios were studied on mechanical properties namely Tensile strength, Percentage of elongation and Hardness and the results were compared. The fracture mechanism of tensile specimens were studied by Universal Testing machine. The tensile strength and hardness Increasing rice husk ash particles in hybrid composites decreases the tensile strength and hardness. Brittle fractures in the form of cracks, and particle fractures were formed due to the solid interfacial bonding between the reinforcements and alloy. Ductile fractures are the reason for high impact strength and are characterised by dimples and voids. The eco-friendly rice husk ash has the potential to serve as reinforcement for the development of hybrid composites.
