多层陶瓷复合材料（MLC）是由两种互不溶的陶瓷材料以对称方式依次堆积而成的复合材料，可分为弱界面多层复合材料和强界面多层复合材料。研制了石墨烯添加的多层陶瓷三明治（GMCS）复合材料。具有5和30wt%石墨烯添加的Si3N4的多层堆叠以夹层结构分层。如此形成的具有5层和7层的多层堆叠通过热等静压（HIP）烧结。研究了石墨烯添加的均匀性、层状结构的影响以及具有较低和较高石墨烯含量的层的位置对最终性能的影响。
The multilayer ceramic composites (MLC) consist of two ceramic materials insoluble in each other and sequentially piled in a symmetric manner whereas they can be divided into two groups: multilayer composites with weak interfaces and composites with strong interfaces. The graphene added multilayer ceramic sandwich (GMCS) composite was developed. The multilayer stack of Si3N4 with 5 and 30 wt% graphene addition were stratified in sandwich structure. So formed multilayer stacks with 5 and 7 layers were sintered by hot issostatic pressing (HIP). The homogenity of graphene addition, the effect of layered structures and the position of layers with lower and higher graphene content on the final properties were studied.
