A brake stack is disclosed. In various embodiments, the brake stack includes a pressure plate; an end plate; a rotor disk disposed between the pressure plate and the end plate, the rotor disk including a rotor core comprising a carbon-carbon material and a boron-containing component; and a stator disk disposed between the pressure plate and the end plate, the stator disk including a stator core comprising the carbon-carbon material and the boron component. In various embodiments, the boron-containing component exhibits a higher heat capacity than a corresponding friction liner that comprises a ceramic matrix composite material, applied by chemical vapor infiltration, and that provides a surface optimized for aircraft brake friction and wear.
