Graphene reinforced ceramic matrix composite (GRCMC) – state of the art

Abstract

Ceramic Matrix Composites (CMC) are widely used for manufacturing automobile parts aircraft components, biomedical and electronic devices. In recent years, graphene has found extensive applications in various fields like effective reinforcement in the development of metal matrix, polymer matrix and ceramic matrix composites. Literature reveals that more focus was on polymer and metal matrix composites reinforced with graphene when compared to ceramic matrix composites. In this manuscript, the effect and suitability of graphene as a reinforcement for fabricating ceramic matrix composite are presented. Further, the property evaluation, including mechanical and physical, characterization and microstructural evaluation of the CMCs developed with graphene as reinforcement is elaborated. The investigation of the reinforcing mechanisms and failure behavior of ceramic matrix composites reinforced with graphene, together with the development of novel processing techniques to solve manufacturing difficulties, are key areas of focus. Although many investigations have concentrated on enhancing the mechanical and electrical characteristics of ceramics by integrating graphene, more investigation is required to investigate the interfacial interaction between graphene and the ceramic matrix, as well as the influence of graphene size on the properties of the composite. Furthermore, there is a need for future research to explore the possibility of using graphene-reinforced ceramic composites in several multifunctional applications, including microwave absorption, electromagnetic interference shielding, ballistic armors, self-monitoring damage sensors, and energy storage and conversion. Future research should focus on developing innovative processing procedures that guarantee the uniform distribution and precise alignment of graphene sheets within the ceramic matrix. The incorporation of graphene into ceramic matrix composites presents novel prospects for augmenting the characteristics and capabilities of ceramics, rendering it a very interesting area for further investigation.
