Methods are disclosed herein to fabricate high-strength ceramic matrix composite (CMC) structures by combining, in one example, pre-impregnated (prepreg) material with a pre-ceramic polymer. The prepreg is processed to a first density, and the densification is completed with repeated polymer infiltration and pyrolysis (PIP) cycles of the pre-ceramic polymer to fabricate a CMC structure. Advantageously, the present invention allows for fabrication of ceramic matrix composites more efficiently and to a larger scale than previously available. |
