Summary

The effect of the addition of glass particles to SiC matrix on temperature dependence of tensile strength has been examined using SiTiCO fiber-reinforced SiC matrix minicomposites fabricated by PIP process. It is found that the addition significantly improves tensile strength of the minicomposite. The tensile strength of the minicomposite at room temperature was = 885 MPa, and the strength reduction at 1273K from that at room temperature is only = 10%. These strength levels are roughly twice of the conventional SiTiCO fiber-reinforced SiC matrix minicomposite fabricated by the same process.
