Preparation and tribological properties of C fibre reinforced C/SiC dual matrix composites fabrication by liquid silicon infiltration

► C/C-SiC brake composites were fabricated by chemical vapour infiltration combined with liquid silicon infiltration. ► The density of C/C-SiC was 2.2 g cm−3 with 6.4% open porosity. ► The flexural and compressive strength of C/C-SiC can reach to 174 and 241 MPa, respectively. ► C/C-SiC with steel opposing material shown advanced tribology.
