Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed: 1. A method for forming a hole within a ceramic matrix composite component, the method comprising: 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. 2. The method as recited in claim 1 , wherein wrapping the first core portion with the first ceramic matrix composite material comprises separating a plurality of fibers around the hollow member. 3. The method as recited in claim 1 , wherein wrapping the first core portion with the first ceramic matrix composite material comprises penetrating the ceramic matrix composite material with the hollow member. 4. The method as recited in claim 1 , further comprising coaxially forming a hole in the first core portion for the rod within a hole in the first core portion for the hollow member. 5. The method as recited in claim 1 , further comprising removing the hollow member and leaving the rod in the first core portion. 6. A method for forming a hole within a ceramic matrix composite component, the method comprising: 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; 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; and burning out the first core portion, the second core portion, the hollow member, and the rod from the ceramic matrix composite material subsequent to wrapping the first core portion and the second core portion with the second ceramic matrix composite material. 7. The method as recited in claim 6 , wherein the hollow member is manufactured of a nylon.
