Abstract

A new type of pure carbon fiber (C_f) preform with complex shape was prepared by gel-casting. C_f/SiC composite with high performance was rapidly prepared by reactive melt infiltration (RMI). The microstructure which determined the mechanical properties of the C_f/SiC composites could be controlled by in-situ fiber coating preparation process. The fracture toughness of the C_f/SiC composite with SiC and PyC coating, 8.3 ± 1.5 MPa m^1/2, was far superior to pure SiC ceramic prepared by RMI. This method showed excellent manufacturing capability and remarkable potential in fabrication of C_f/SiC composites with complex shape and high mechanical performance.
