AbstractHerein, we describe the synthesis of multifunctional silicon carbide matrix composites by the in-situ growth of SiC in three-dimensionally printed graphene scaffolds by chemical vapor infiltration (CVI). Graphene-based scaffolds with various graphene contents, which are first assembled by three-dimensional (3D) printing, exhibit good adhesion and interlayer bonding. The content and morphology of the SiC matrix in the composite is controlled by optimizing the values of the CVI parameters, such as the holding time and gas pressure. The 3D graphene/SiC multifunctional composites exhibit outstanding mechanical performance, delivering a maximum compressive strength of 193 +/- 15.7 MPa, which is 394% higher than that of the directly mixed product. The toughening mechanism induced by the graphene sheets, including pull-out and crack deflection, are clearly observed. The combination of 3D graphene scaffold and SiC matrix generates a larger number of conductive channels and provides a material that outperforms traditional ceramic materials in terms of electrical conductivity. It is expected that high-performance 3D graphene reinforced ceramic matrix composites with structural and functional integration will be prepared by introducing ceramic matrices into 3D graphene scaffolds.
