The practical work carried out as a part of research in the field of carbon nano tube (CNT) metal matrix composites (MMCs). Much research has been undertaken in utilising CNTs as reinforcement for composite material. However, CNT-reinforced MMCs have received the least attention. These composites are being projected for use in structural applications for their high specific strength as well as functional materials for their exciting thermal and electrical characteristics. The present work focuses on the critical issues of CNT-reinforced MMCs that include processing techniques, nano tube dispersion, interface, strengthening mechanisms and mechanical properties. Samples are prepared after the fabrication process and the mechanical property improvements achieved by addition of CNTs in various metal matrix systems are summarised. The factors determining strengthening achieved by CNT reinforcement are tested for the structural and chemical stability of CNTs in different metal matrixes. The importance of the CNT/metal interface has been reviewed. The importance of CNT dispersion and its quantification is highlighted. Tensile, hardness, X-ray Radiography, and conductivity tests are processed to find out exact results for further research.
