Silicon carbide framework reinforced aluminum alloy brake disc with bosses and through holes

The utility model relates to a silicon carbide skeleton reinforced aluminum alloy brake disc with a boss and a through hole, which comprises a silicon carbide skeleton and an aluminum alloy base body, the aluminum alloy brake disc is divided into three layers, the upper layer is composed of the boss of the silicon carbide skeleton and continuous phase aluminum alloy, and the middle layer is composed of the silicon carbide skeleton of the through hole and aluminum alloy filled in the through hole. The lower layer is aluminum alloy. The silicon carbide framework is located in the aluminum alloy base body and comprises a grid structure composed of through holes and silicon carbide hole walls, bosses are formed in the grid structure, holes used for being filled with the aluminum alloy base body are formed in the middle of the grid structure, and the holes are of a vertically-through structure. The holes are filled with the aluminum alloy base body, the aluminum alloy base body is of an integrated continuous struc
