Glass-ceramic matrix composite feedstock and forming

A method of forming a glass-ceramic matrix composite part, the method comprising:

• forming a consolidated feedstock material in a predetermined shape, wherein forming the consolidated feedstock material comprises:
• sourcing a ceramic fiber and a glass matrix material that are unconsolidated and include ceramic fibers arranged in a unidirectional fiber tape, woven fabric, or combination thereof;
• loading the unconsolidated ceramic fiber and glass matrix materials into a first tooling;
• and
• applying heat and pressure to the unconsolidated ceramic fiber and glass matrix materials to form a consolidated feedstock material with corrugations;
• and
• forming a consolidated glass-ceramic matrix composite part, wherein forming the consolidated glass-ceramic matrix composite part comprises:
• sectioning the consolidated feedstock material to produce a plurality of consolidated feedstock material pieces wherein the plurality of consolidated feedstock material pieces has corrugations;
• assembling the plurality of consolidated feedstock material pieces and a first unconsolidated reinforcing material into a composite layup, the first unconsolidated reinforcing material comprising one or more unconsolidated layers of unidirectional fiber tape or woven material with glass powders, and wherein the plurality of consolidated feedstock material pieces and first unconsolidated reinforcing material are disposed in a die tooling with a plurality of mandrels disposed between the plurality of consolidated feedstock material pieces, the plurality of mandrels aligned in a parallel direction with the corrugations of the plurality of consolidated feedstock material pieces;
• and
• applying heat and pressure to the composite layup to fuse the consolidated feedstock material pieces and the first unconsolidated reinforcing material and form the consolidated glass-ceramic matrix composite part with embedded channels, wherein the orientation of the ceramic fibers of the consolidated feedstock material pieces is maintained during the steps of assembling and applying heat and pressure.
