Synthesis and characterization of Al-CNT-TiO2 nano composite and some of its properties

In this study, synthesis of Al-TiO2-multi wall carbon nanotubes composite and effect of multi-wall carbon nanotube (MWCNT) on AL-Tio2 composite has been investigated. Mechanical alloying has been used to mix powders of aluminium, TiO2 powders and multi-wall carbon nanotubes. TiO2 in the amount of 1%,2% and 3% and carbon nanotubes with 0.5,1,1.5 and 2 wt% was used. Some properties of different samples of this composite was tested and the results showed that the addition of MWCNTs improved properties such as tensile strength and micro hardness and investigation of microstructure by transmission electron microscopy (TEM) showed that CNTs dispersed homogeneously in the Al-TiO2 matrix.
