Version of Record

In recent years, carbon nanotube (CNT) has been attractive to be used for reinforcements in metal matrix composites (MMCs) to be applied to structural members because CNT has distinguished characteristics such as lightweight, high elastic modulus, high strength and others. However, wider application of CNT and its composites has not been achieved due to difficulty to disperse CNT in the MMCs to efficiently obtain the expected excellent properties. In this study, CNT was uniformly dispersed using chemical and mechanical treatments, such as an ultrasonic treatment with dispersant in an organic solvent, a dry ball milling and post-sintering hot rolling. CNT/Al composites were consolidated by spark plasma sintering (SPS). The effect of these treatments on state of dispersion of CNT and mechanical properties of the composites was investigated. Microstructures of the composites were observed using a scanning electron microscope (SEM) with EDS, and transmission electron microscope (TEM). The mechanical properties were investigated on Vickers hardness and anisotropic tensile behavior.
