Abstract:
A method for forming a ceramic matrix composite (CMC) component with an internal cooling channel includes forming a first fiber member, forming a first depression in a surface of the first fiber member, covering the first depression with a second fiber member to form a near-net shape fiber preform of a component with an internal channel defined in part by the first depression, and densifying the fiber preform.
