本文研究了莫来石陶瓷细粉与金属铝复合的摩擦材料，实验证明，莫来石粉对金属铝有明显的增强、增加硬度、提高耐磨性等作用；同时添加石墨、磷酸铝等材料，可进一步改善这种复合材料的其它性能 In this paper, the friction material of mullite ceramic powder and metal aluminum composite was studied. The experiment proved that the mullite powder has a significant enhancement on the aluminum metal, increase the hardness and improve the wear resistance; at the same time, add graphite, aluminum phosphate and other materials, Can further improve the other properties of this composite material
