Study on Aluminum Matrix Composites Reinforced with Singly Dispersed Carbon Nanotubes

Abstract

Using carbon nanotubes (CNTs) as a reinforcement in metal matrix composites (MMCs) is a concentrated topic for materials and processing design in the area of composites science. In this paper, we review our recent development on CNT reinforced powder metallurgy aluminum (Al) MMCs, including the significant issues of processing, microstructures and properties. Main findings on CNT dispersion, composite consolidation, interface microstructures and strengthening mechanisms are introduced.
