The porous C/C body of pyrolytic carbon and asphaltic carbon was respectively introduced into the porous C/C body by needling and fine woven puncture structure. The C/C-ZrC composites were prepared by reacting melt infiltration （RMI） process with molten metal Zr. The effects of preform structure and matrix carbon type on the microstructure and mechanical properties of C/C-ZrC composites were studied. The results show that the material is only composed of C and ZrC phases after melting， the porosity is between 5% to 10%， and the mass fraction of ZrC is between 53% to 63%. The C/C body with needled structure has better melting effect， and the C/C-ZrC composite with the highest density reaches 3.21 g/cm³. The ZrC mass fraction reaches 62.8%. The pyrolysis carbon matrix has a better protective effect on the fiber during the melting and infiltration process， and the bending strength of C/C-ZrC composites reaches 148 MPa and the compression strength reaches 408 MPa.
