| Abstract Scope |
The fabrication of aluminium matrix composites with lightweight nano-reinforcements has proven to be very attractive due to their superior properties. In the present study, Carbon Nanotubes (CNTs) and Graphene Nanoplatelets (GNPs) have been incorporated into an aluminium matrix using the Spark Plasma Sintering (SPS) process. Composite samples with varying wt.% of CNTs and GNP (0.1-0.5 wt.%) were prepared and the effect on the mechanical properties investigated. The microstructural evolution and the yield strength of each sample were evaluated and compared with neat reference samples. It was established that the CNTs reinforced nanocomposites exhibited a relatively higher yield strength than the GNP reinforced. An improvement by 13% and 18% respectively for additions of 0.5 wt.% CNTs was found. Based on the results, the presence of a 2-D planer geometry is modelled and discussed in view of its ability to enables a more efficient network at low wt.% of the fillers. |
