C sf /SiC multilayer composites for thermal conductivity ( TC ) test in three directions were successively prepared by tape casting and pressureless sintering. After 1500°C/5 h oxidation treatment, short carbon fibers were oxidized which produced many pores. However, a core area, which was composed by short carbon fiber, SiC, and few SiO 2 , was still observed. TC properties of C sf /SiC multilayer composites were highly anisotropic. The TC was decreased with the increase in fiber amount. C sf /SiC multilayer composites demonstrated the highest TC along the tape casting direction and the lowest TC through the thickness direction, which is favorable for thermal protection purpose.
