Silicon carbide possesses many unique properties like superior strength, corrosion and oxidation resistance at elevated temperature [1]. Silicon carbide in the fibrous form is employed for the development of ceramic-matrix and metal- matrix composites (CMCs and MMCs) [2, 3]. Recently there is growing interest in the synthesis of nanofibres, which could be used for the development of nanocomposites, solid-state lubricants, catalysts and components of magnetic devices [4]. Nano silicon carbides are synthesized as nanorods, nanowires, nanotubes and nanofibres [5, 6, 7, 8]. Silicon carbide nanomaterials which can be used as reinforcing material are generally prepared by chemical vapor deposition (CVD) [9], arc-discharge [10], polymer blend technique [11] and by reaction between carbon nanotubes and silicon monoxide [12]. The authors had also employed and reported polymer blend technique for the development of pitch based carbon fibres [13, 14]. It was seen by the authors during their...
