Abstract
Different Aluminum-exfoliated graphite nanoplatelets particles (xGnPs) composites, namely Al-0.0wt.%xGnP, Al-1.0wt.%xGnP, Al-3.0wt.%xGnP, and Al-5.0wt.%xGnP, were fabricated using powder metallurgy technique. The mixture powders were consolidated at 500 MPa for 5min followed by pressure-less sintering at 400, 500 and 600 degrees C for 5 h. The compression, density, fracture surface, and hardness measurements were performed in order to evaluate the mechanical properties of the different Al-xGnP composites. Results showed that the compressive strength and Vickers hardness increase, while the density decreases as a function of exfoliated graphite nanoplatelets content. The best condition was reached by sintering at 600 degrees C for 5h for all composites.
