Preparation and Mechanical Property of MWNTs/Al Composite Wires by Rotational Friction Extrusion Processing

Abstract:

The multi-walled carbon nanotubes (MWNTs) reinforced aluminum composite wires were fabricated by Rotational Friction Extrusion Processing (RFEP). The microstructure and mechanical properties of MWNTs/Al composite wires with different content of MWNTs were investigated. The results show that carbon nanotubes were well dispersed into the aluminum matrix, and the mechanical properties of MWNTs/Al composit wires were improved by FSP and RFEP. The tensile strength reached up to 186.3MPa when 4.5vol% MWNTs was added, which was 1.13 times that of MWNTs/Al composite blocks prepared by FSP only.
