Abstract

Carbon-nanotube-reinforced Cu matrix nanocomposites have been fabricated by molecular-level mixing of functionalized carbon nanotubes (CNTs) with Cu ions, followed by spark plasma sintering. The compressive strengths and Young's moduli of CNT-reinforced nanocomposites are considerably higher than those of the Cu matrix due to the homogeneously dispersed CNTs embedded in the Cu matrix.

Keywords: Carbon nanotube composites; Carbon nanotubes, multiwalled; Nanocomposites.
