Abstract: Graphite/Al composites are generally required to be prepared at high temperatures,and graphite particles or fibers and aluminum matrix will have different degrees of wetting and interfacial reaction,which forms the interface of different structures. Wettability and interfacial reaction between the two phases play an important role on the final performance of composites.The key to obtain high performance graphite/aluminum composite materials is to study the wetting mechanism in depth and the effective control of interface reaction. This paper analyzed and discussed the development situation and preparation process of graphite/aluminum composite. In the process of preparation,the interface problem and the defects of pores were analyzed,and the countermeasures were discussed. The application prospect of this new type of composite material was prospected.
