摘要：

A SiC fiber reinforced SiC composite with magnesium-silicon-based oxide interphase was fabricated by the chemical vapor infiltration process and its mechanical properties were evaluated. An interphase was prepared on the advanced SiC fiber, Tyranno SA, using the alkoxide method. The tensile strengths of SiC fiber with the Mg-Si-O coating retained at 85% or higher compared to uncoated-un heated fiber after heating below the 1300 degrees C, while strength were slightly degraded to 80% after heating at 1400 degrees C. The composite showed ductile failure behavior and the fiber pull-out effect was observed in the fracture surface of the composite. (c) 2007 Elsevier B.V. All rights reserved.
