Metal Matrix/Nanocarbons Composites Based on Copper and Aluminum

Abstract

Metal matrix composites possess high-temperature capability, high thermal conductivity, low thermal expansion coefficient, and high specific stiffness and strength. Recently discovered carbon nanostructures such as carbon nanofibers (CNFs), nanotubes (CNTs) and graphene are promising components for next-generation high-performance structural and multifunctional composite materials. Here, we utilized new approach to fabricate composite materials on the basis of aluminum, and copper matrix. In this chapter we summarize our knowledge and also present new results on the preparation of a good dispersion of CNTs, CNFs and graphene in a matrix, with the intention of improving the mechanical or electrical properties of metal-carbon composite nanomaterials. This study shows the way to solve one of the largest problem to creating strong, electrically or thermally conductive CNT/CNF or graphene composites: the difficulty of achieving a good dispersion of the carbon nanomaterials in a metal matrix. We show that discontinuously reinforcement can be successfully developed for industrial applications.
