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.

A friction disk, comprising:
- a first wear surface formed from a carbon fiber-carbon matrix composite material;
- and
- a first wear plug located in a first opening defined by the carbon fiber-carbon matrix composite material, wherein the first wear plug extends axially from the first wear surface, and wherein the first wear plug includes at least one of:
- a graphite rod, and
- a first wear particulate and a binder, the first wear particulate including graphite powder, a mixture of graphite powder and ceramic powder, or carbon pitch particulate.
