Abstract
A friction disk may comprise a first wear surface formed from a carbon fiber-carbon matrix composite material. A wear plug may be located in an opening defined by the carbon fiber-carbon matrix composite material. The wear plug may extend axially from the wear surface. The wear plug may comprise a rod or a particulate.
Claims4
A method of making a carbon fiber-carbon matrix composite part, comprising:
- densifying a fibrous preform by chemical vapor infiltration (CVI) to form a densified fibrous preform;
- forming a first opening in a first wear surface of the densified fibrous preform;
- and
- inserting a first wear plug in the first opening, wherein the first wear plug includes:
- a graphite rod;
- a binder, and
- a first wear particulate, the first wear particulate including at least one of graphite powder, a mixture of graphite powder and ceramic powder, or carbon pitch particulate.
