利用真空压力浸渍工艺制备了ＳｉＣｐ增强和ＳｉＣｐ、Ｇｒ（石墨）混杂增强铝基复合材料，Ｇｒ能降低复合材料的摩擦系数，减少偶件的磨损，但Ｇｒ的片状和针状外形对其耐磨性不利。
SiCp reinforced and SiCp, Gr (graphite) hybrid reinforced aluminum matrix composites were prepared by vacuum pressure impregnation process. Gr can reduce the friction coefficient of the composite and reduce the wear of the coupled components. However, Grinding bad.
