Abstract

Silicon carbide (SiC) fibers exhibit excellent heat and chemical resistance at high temperatures. In this study, polycarbosilane melt spinning, oxidation curing, and pyrolysis were performed to fabricate amorphous SiC fibers, and their resistance heating characteristics were evaluated. A stick-type amorphous silicon carbide fiber heating element was manufactured, and the resistance was measured using the two-point probe method. The structural, electrical, and heating characteristics were evaluated at different pyrolysis temperatures. The fiber produced at 1300°C displayed the highest conductivity and the maximum heating compared to the fibers produced at 1200°C and 1400°C. This may be attributed to difference in the structures of the fibers, particularly the SiC and graphitic carbon structures.
