The effect of low-cycle fatigue loading on interlayer strength and fracture toughness of discretely reinforced carbon-carbon composite material (CCCM) for friction use is studied. The material demonstrates good resistance to fatigue loads. In the described mechanisms for increasing CCCM fracture toughness after applying fatigue load, the fiber–matrix interface plays a key part. The dependences of CCCM fracture toughness and interlayer strength on the fatigue loading parameters are determined.
