An Effect of SiO2 and Carbon Nano Tubes on Mechanical Properties of LM-12 Aluminium Alloy Hybrid Metal Matrix Composite

The present research is aimed to develop hybrid metal matrix composite using aluminium alloy LM-12 reinforced with constant weight percentage (9%) of SiO2 and different weight percentage (wt %) carbon nano tubes. After casting different mechanical tests were conducted such as Tensile strength, Hardness and Microstructure analysis of Hybrid Metal Matrix Composite developed experimentally. The method of developing and producing new composite material using a sand mould is by stirring casting method then allowed to solidify. Tests such as tensile test, hardness and microstructure analysis are to be performed on different specimens within the casting. The composite materials so produced are tested for their mechanical properties according to ASTM standards.
