Tensile fracture behavior of two dimensionally reinforced Si-Ti-C-O fiber bonded ceramics (FBC) was investigated. Stress-strain curve of the FBC was linear up to 120 MPa, and showed nonlinear behavior in the higher stress level. Micro-fracture in 90° layers, such as delamination at the fiber/ matrix interface, was observed by the SEM. It was shown that evolution of the micro-fracture was closely related to the degradation in Young's modulus.
