  • ADVANCED POLYMER IMPREGNATION AND PYROLYSIS OF CERAMIC MATRIX COMPOSITES
    Publication number: 20260146007
    Abstract: A method of manufacturing a ceramic composite includes: prepregging a plurality of porous fiber cloths, a powder compact, a combination thereof, or additively-manufactured matrix and fibers, with a preceramic polymer composition to form a preform composite body; curing the composite body followed by pyrolyzing the cured composite body to obtain a ceramic composite body; densifying the ceramic composite body by sequentially performing a plurality of densification cycles to obtain a densified ceramic composite body, wherein each densification cycle includes: submerging the ceramic composite body in the preceramic polymer composition to impregnate the ceramic composite body; subjecting the impregnated ceramic composite body to a vacuum; curing the impregnated composite body; and pyrolyzing the impregnated composite body; and subsequently crystallizing the densified ceramic composite body. The preceramic polymer composition comprises a preceramic polymer component, a crosslinker, and a catalyst.
