Abstract

The research study is use CNTs-Al composite material for the right engine mount which which is A356 aluminium alloy reinforced with 0.5% multi-walled carbon nanotube (MWCNTs) and a premix of 0.5% magnesium (Mg) as wettability agent. Basically, in automotive industry the development of new features and technology are increasing. So with the additional of new features and technology to the car, the additional of weight is gained. Thus, it is very important to consider the reduction of weight car in order to give more efficiency to the fuel consumption and also reduce waste energy. Based on objective of the research, the study is more to the CNTs-Al composite material strength, sand casting process and also secondary process T6 heat treatment process. In literature review, the data and information obtained shows the strength and hardness of CNTs-Al composite is increased through secondary process. So the results obtained has proved that in the analysis of hardness, scanning electron microscope, optical microscope and tensile test shown the CNTs-Al composite has increased their strength and hardness after the T6 heat treatment. This is because the microstructure of heat treated α Al has less dendritic because of grain structure was smalling. Tensile test also shown the increasing of ultimate tensile strength and elongation percentage of heat treated CNTs-Al composite. Thus, the new front lower control arm has the weight about 0.345 kg so it achieved the aim of this research.
