1. 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.
