The effect of nickel interface layer on the mechanical properties of SiC fiber / SiC matrix composites was examined. Pure nickel was plated on the surface of SiC fiber (Tyranno Lox-M fiber) using non-electrolytic plating method. Amorphous SiC (Si-C-0) matrix was formed using polymer impregnation and pyrolysis (PIP) process of poly-titano-carbosilane (PTCS). Flexural tests were carried out at room temperature to evaluated the mechanical properties. The resultant SiC/SiC composites exhibit nonlinear load-displacement behavior before the final failure. Pullout behavior of SiC fibers was clearly observed at the fracture surfaces. The experimental results suggest that the suitable interfacial properties were achieved applying a nickel interface layer between SiC fiber and Si-C-0 matrix.
