C_f/C-ZrC-SiC composites were fabricated via reactive melt infiltration （RMI） with stitched carbon fiber preform and Si-Zr alloy as reactants. The microstructure of C_f/C-ZrC-SiC composites was analyzed by SEM-EDS and XRD. It can be concluded that SiC-ZrC ceramic matrix has uniform distribution in the C_f/C-ZrC-SiC composites. Benefiting from the above matrix microstructure， the bending strength and modulus of C_f/C-ZrC-SiC composites can reach up to 323.2 MPa and 46.6 GPa， respectively. The mass ablation rate and linear ablation rate of C_f/C-ZrC-SiC composites with high ZrC content are 1.263 mg/s and 2.367 μm/s， respectively； and 2.056 μm/s and 5.067 mg/s for C_f/C-SiC-ZrC composites with less ZrC content， respectively. C_f/C-ZrC-SiC composites show good ablation resistance.
