Pre-form ceramic matrix composite cavity and method of forming a ceramic matrix composite component

摘要

A pre-form CMC cavity and method of forming pre-form CMC cavity for a ceramic matrix component includes providing a mandrel (110), applying a base ply (112) to the mandrel (110), laying-up at least one CMC ply (114) on the base ply (112), removing the mandrel, (110) and densifying the base ply (112) and the at least one CMC ply (114). The remaining densified base ply (112) and at least one CMC ply (114) form a ceramic matrix component having a desired geometry and a cavity formed therein. Also provided is a method of forming a CMC component.
