Abstract In this paper, graphene contained SiCf/SiC composites were prepared by a two-step process, with graphene/SiC slurry introduced by slurry brushing first, then followed a chemical vapor infiltration of SiC matrix. The effects of graphene mass fraction in the slurry on the microstructure, mechanical properties and thermal conductivity of SiCf/SiC composites were studied by using scanning electron microscopy, three-point bending test and laser flash apparatus. The results show that, when the mass fraction of graphene is 2%, the distribution of graphene in the slurry layer is uniformly, resulting in the highest thermal conductivity of 13.14 W/(m·K) of the composites. With the increase of the mass fraction, the distribution of graphene in the slurry layer is deteriorated, which leads to a decrease of the density and thermal conductivity of SiCf/SiC composites. However, although graphene begins to agglomerate at a mass fraction of 4%, the composites possess the highest flexural strength of 328.12 MPa, due to the well bonding between graphene and the SiC matrix.
