Description

The development of aluminum-carbon nanotubes (Al-CNT) composites has seen a surge in interest following promising results reported by various groups. The latest enhancements achieved by the research group: an increase in tensile strength and Young's modulus of 69% and 23% respectively for Al-CNT composites with 5 wt. % MWCNT were accompanied by a reduction in ductility expected to limit the applications of these novel composites. This is currently being addressed through the use of (1) dual matrix approach in which the CNTs are embedded in a first matrix of aluminum powders which are consequently embedded in a second matrix of aluminum; (2) functionally-graded (FG) approach in which a gradual change in the composition of the CNT-reinforced regions is tailored so as to produce a design-efficient material with an ultra hard surface that gradually leads to a soft core. The two approaches aim at enhancing the formability of the material for wider industrial applications.
