Quasi-three dimensional needled C/ C-silicon carbide thin-wall throats were prepared by CVI+PIP combined process. The performs were spreading individually by carbon cloth layers which is copying the inner moulding surface of the throat and 30° carbon cloth layers which is the same as the entrance angle of the throat. The effect of the two carbon cloth spreading means on the bending performance, integral bearing performance and anti-ablative and erosion properties of C/ C-SiC components are investigated. Results show that the bending intensity of the components is 205 MPa and 152 MPa and the hydraulic bursting pressure is 6. 5 MPa and 4. 9 MPa separately. The ablation properties are investigated using oxyacetylene ablation technique with the angle between the gas flow and material surface is 30°. The anti-ablative and anti-erosion properties of 30° carbon cloth spreading composites is excellent. The linear ablation rate is 70% compared to that of carbon cloth copying spreading composites after 200 s ablation time.
