SiC/SiC-O composites with high oxidation resistance were synthesized through Sol-Gel route with low environmental load. In the present study, SiC fibers were coated with thin C-layer in order to weaken the fiber/matrix interfacial shear strength. In order to coat C-layers, SiC fibers were dipped into epoxy resin/acetone solution and heat treated at 1000℃ for 2h. The weight ratio of epoxy resin to acetone was selected as 0%, 10% and 20% to confirm the effect of C-layer thickness on the mechanical properties. Tensile strength of SiC/SiC-O composites with C-layers were higher than that of SiC/SiC-O composites without C-layer. High oxidation resistance were also observed for SiC/SiC-O composites with and without C layers.
