Abstract
A brake disk may comprise a friction disk formed of at least one of a carbon fiber-ceramic matrix composite material or a carbon fiber-carbon matrix composite material. A first surface of the friction disk defines a first recess. A first ceramic insert comprising ceramic powder may be located in the first recess.
Claims16
A brake disk, comprising:
- a first friction disk formed of at least one of a carbon fiber-ceramic matrix composite material or a carbon fiber-carbon matrix composite material, wherein a first surface of the first friction disk defines a first recess, the first surface extending from an inner diameter to an outer diameter of the first friction disk;
- a first ceramic insert comprising ceramic powder located in the first recess;
- and
- a second ceramic insert located in a second recess of the first friction disk, wherein the second recess is defined by a second surface of the first friction disk, the second surface being oriented away from the first surface,
- wherein the first friction disk comprises at least one of a rotor core or a stator core.
