Abstract
Silicon carbide nanofiber and carbon nanotubes are introduced. The structure and application of nanotubers (nanofibers) in carbon/carbon composites are emphatically presented. Due to the unique structure of nanotubers (nanofibers), they can modify the microstructure of pyrocarbon and induce the deposition of pyrocarbon with high text in carbon/carbon composites. So the carbon/carbon composites modified by CNT/CNF have more excellent properties.
Highlights
Since the discovery of carbon nanotubes (CNT) by Japanese expert Iijima in 1991, the studies on CNT have been the frontier and hot in the field of new materials [1,2,3]
CNT has a large number of unique advantages, such as high aspect ratio, large surface area, excellent mechanical properties, and unique heat properties, so it is suitable for the reinforcement of composite materials [4, 5]
Silicon carbide whisker (SiCW) and Silicon carbide nanofiber (SiCNF) are a new type of ceramic fiber, which can prepared by the similar method as that of CNT
Summary
Since the discovery of carbon nanotubes (CNT) by Japanese expert Iijima in 1991, the studies on CNT have been the frontier and hot in the field of new materials [1,2,3]. Silicon carbide whisker (SiCW) and Silicon carbide nanofiber (SiCNF) are a new type of ceramic fiber, which can prepared by the similar method as that of CNT. Compared with CNT, SiCW/SiCNF has more excellent mechanical, heat, electricity properties, and better physicalchemical stability [6,7,8]. A carbon/carbon (C/C) composite is the carbon fiber reinforced carbon matrix composite Due to their low density, excellent mechanical and thermal properties, C/C composites have been widely used in aviation and space industries for rocket nozzles, missile nosetips, re-entry heatshields, nose and leading edges of space shuttle, brake discs for aeroplane, and so forth [9, 10]. Due to the unique properties of nanotubes/nanofibers, fiber surface modification by CNT/SiCNF is a good research direction. The main preparation methods of CNT are arc discharge, catalysis decomposition, laser evaporation, and plasma method [16,17,18]. The mature technology are the discharge of graphite arc and catalysis decomposition of hydrocarbons
