Abstract

With multi-walled carbon nanotubes (MWCNTs) as reinforcement, MWCNT/alumina composites were prepared at the MWCNTs mass% of 0.5. A flexural strength of 572.1±28.3MPa and fracture toughness of 4.80±0.42MPam ^1/2, 1.2 times that of MWCNT-free monolithic alumina prepared under the same processing condition, was achieved. Experimental results showed that the dispersibility of the MWCNTs in the composite was crucially important in order to improve the mechanical properties of the MWCNT/alumina composite material.
