EVALUATION OF MECHANICAL PROPERTIES OF ALUMINIUM ALLOY REINFORCED WITH RICE HUSK ASH AND GRAPHENE HYBRID METAL MATRIX COMPOSITE

ABSTRACT

Composites have been developed with great success by the use of reinforcement. Monolithic materials cannot possess all the properties to be obtained hence, the need to employ the use of composite materials. Aluminum is generally utilized as a basic material particularly in the aerospace industry in view of its light weight property Be that as it may; the low quality and low melting point were continuously an issue.However due to these limitations, intense exploration on the use of metallic matrices has ensued, particularly with respect to aluminium. Metal matrix composites reinforced with particles such as SiC provides significantly improved mechanical properties, high bonding strength and high wear resistance. In this study the effect of rice husk ash and graphene reinforcement in the Aluminium (Al) matrix was investigated.

Rice husk ash (RHA) with high silica content up to 97,095% was used for the study with the RHA varied from 5vol% - 15vol% at intervals of 5vol% at different weight sizes of 150µm, 300µm and 600µm in aluminium alloy as reinforcement. Also graphene of constant volume percentage of 0.5vol% was used for the study. The mechanical properties of the composites including tensile strength, impact strength, hardness and fatigue strength were investigated also with the microstructure test, scanning electronic microscopy (SEM) Analysis and Phase analysis (XRD Analysis). The aim of the paper is to fabricate Metal matrix composite (MMC) of aluminium alloy reinforced with rice husk ash and grapheme and reducing the negative environmental impact on the society due to improper disposal, improving the economic utilization of rice husk and aluminium matrix composite and developing new materials with superior mechanical properties. In conclusion the melting point, Stiffness, and wear resistance was improved maintaining its lightness.
