Abstract
A method for forming a ceramic sandwich-structured composite component includes applying one or more ceramic matrix composite (CMC) plies to a surface of a tool, and positioning a ceramic foam precursor with respect to the tool such that the ceramic foam precursor and the one or more CMC plies is disposed in a sealed interior cavity of the tool. The ceramic foam precursor and the one or more CMC plies are cured within the sealed interior cavity to form a green preform such that the ceramic foam precursor expands within the sealed interior cavity to apply a pressure to the one or more CMC plies to consolidate the one or more CMC plies. The expanded ceramic foam precursor forms a ceramic core of the green preform bonded to the one or more CMC plies. The green preform is removed from the tool and sintered to ceramify the green preform.
