Abstract

This paper describes the mechanical properties of multi-walled carbon nanotube (MWCNT)/alumina composites prepared by a novel flocculation technique and spark plasma sintering (SPS) method. The influences of processing parameters including sintering temperature, acid treatment temperature and MWCNT volume fraction on the composites' mechanical properties were investigated. It is found that the well dispersed MWCNTs within the alumina matrix were obtained in the high volume fraction MWCNT composites prepared in this research. Lower sintering temperature and higher acid treatment temperature could lead to the maintenance and increase of bending strength and fracture toughness with the MWCNT fraction of 5 vol.%, even 10 vol.%.
