Abstract
A method for forming a hole within a ceramic matrix composite component includes forming a first core portion for a ceramic matrix composite component; embedding a hollow member into the first core portion at a desired location; wrapping the first core portion with a first ceramic matrix composite material; inserting a rod through the hollow member and into the first core portion; removing the hollow member; assembling a second core portion to the first core portion such that the rod extends into the second core portion; and wrapping the first core portion and the second core portion with a second ceramic matrix composite material.
Claims12
A core for a ceramic matrix composite component, comprising:
- a first core portion;
- a second core portion spaced from the first core portion to define a space between the first core portion and the second core portion;
- and
- a rod extending from within the first core portion across the space and to and within the second core portion, wherein the first core portion comprises a hole for the rod coaxial within a hole for a hollow member.
