摘 要：Graphene nanoplatelets（GNPs） are considered to be one of the most promising new reinforcements due to their unique two-dimensional structure and remarkable mechanical properties. In addition, their impressive electrical and thermal properties make them attractive fillers for producing multifunctional ceramics with a wide range of applications. This paper reviews the current status of the research and development of graphene-reinforced ceramic matrix composite（CMC） materials. Firstly, we focused on the processing methods for effective dispersion of GNPs throughout ceramic matrices and the reduction of the porosity of CMC products. Then, the microstructure and mechanical properties are provided, together with an emphasis on the possible toughening mechanisms that may operate. Additionally, the unique functional properties endowed by GNPs, such as enhanced electrical/thermal conductivity, are discussed, with a comprehensive comparison in different ceramic matrices as oxide and nonoxide composites. Finally, the prospects and problems needed to be solved in GNPs-reinforced CMCs are discussed.
