Abstract

Characterization of the Aluminium LM6 composites reinforced with iron oxide (?-Fe2O3) particles and MWCNT under different compositions to investigate their physical, mechanical and electromagnetic properties. Tests were performed under room conditions and significant observations were made based on the micro-structure, hardness, wear, impact and electromagnetic interference (EMI) shielding effectiveness. Observations yield that the presence of iron oxide particles and MWCNT in Aluminium matrix affects EMI shielding property of the composite in X-band (8-12 GHz) frequency range. The reflection and absorption coefficients have shown reflection dominated electromagnetic energy attenuation of the composite samples. The hardness, impact strength and the wear rate of the material was found to increase while as the strength of the composite was compromised. Furthermore incorporating MWCNT along with iron oxide reduced density of the composite, though its addition not proving to be beneficial from the mechanical perspective. The effect of dispersants on the distribution of reinforcements and the controlled distribution of MWCNT is further to more research and discussion.
