Abstract:
A method for producing a composite fiber with a second phase dispersed within a matrix fiber having a heat resistance property,wherein the matrix consists of a substance selected from the group consisting of alumina, zirconia, mullite, YAG, silica, magnesia, nitrides, carbides, metals, alloys, and polymers, andthe second phase consists of a substance selected from the group consisting of zirconia, mullite, YAG, and other oxides of ceramics, or from the group consisting of nitrides, carbides, and metals,which comprises the following steps:adding a stabilizer to a matrix starting solution,mixing the matrix starting solution with a second phase starting solid substance to form a mixture,heating the mixture to produce a precursor solution, synthesizing a fiber from said precursor solution, and then heating the fiber to obtain a composite fiber with the second phase dispersed within the matrix.
