A review on the processing technologies of carbon nanotube/silicon carbide composites

Due to the extraordinary electronic, mechanical, chemical, thermal, magnetic, and optical properties, carbon nanotube (CNT), an excellent one-dimensional nano-material, has been considered as a new filler for polymer, metal, and ceramic matrix composites with the main purpose of improving their mechanical performance, fracture behavior, and functional features. In the silicon carbide (SiC) ceramic field, there are many CNT reinforced SiC ceramic matrix composites and CNT/SiC hybrid structures, which have been investigated successfully using various of methods. This paper reviews the current status of researches and describes all different routes for effectively dispersing CNTs throughout SiC ceramic matrix, densifying composites, and synthesizing hybrid structures.
