Keywords: , , , ,

Carbon Nanotubes (CNTs) are attracting increasing interest as constituents of composite materials for a wide range of applications. MWNT (multi-walled CNT)-ceramics composites are in the beginning of research. The mechanical properties of MWNTs-SiO2 composites were studied in our previous work. The aim of recent work is to develop new systems of composites and extend the potential application of advanced engineering ceramics. In this paper, MWNTs-mullite composites were firstly fabricated with HP (hot-pressing) and SPS (Spark plasma sintering). The microstructures of the composites were observed by FESEM (Field emission scanning electronic microscopy), furthermore, the mechanical and electrical properties of the composites were tested. The work is in progress to prepare new composites that could benefit from the properties of the nanotubes, paving the way for further research in the MWNTs-ceramics composites.
