Carbon-carbon brake pad

The utility model relates to the technical field of brake pads, in particular to a carbon-carbon brake pad which comprises a mother ring, the mother ring comprises a plurality of brake pads which are integrally formed in the axial direction of the mother ring, and the two end faces of each brake pad are brake surfaces of the brake pads. Wherein the mother ring comprises a plurality of pre-tightening carbon layers which are sequentially wound from inside to outside, and the adjacent pre-tightening carbon layers are connected into a whole through needling. The device has the beneficial effects that in the process of winding the pre-tightening carbon layer to form the mother ring, the pre-tightening force (tension force is applied during needling) is applied to the pre-tightening carbon layer, so that the layering phenomenon of the wound and formed mother ring is avoided, and the mother ring (an annular carbon-carbon product) is further manufactured; according to the utility model, the female ring (annular carbo
