  • Silicon carbide (SiC) fibres exhibit high specific strength and oxidation resistance at high temperatures. These properties allow them to be used widely as a reinforcement material in ceramic matrix composites (CMCs) that are employed at high temperatures. Thus, technology for the fabrication of SiC fiber has been focused in various fields. SiC fibres are usually produced from a polycarbosilane (PCS) precursor by a process that involves the following three stages: melt spinning, curing, and sintering. In our laboratory, optimizing nanostructure of SiC fibers has been investigated by controlling each stage for manufacturing SiC fibers with high strength and usability at high temperature.
