Hypersonic reentry process, exposure to the environment is very harsh, especially the leading edge of the wing tip and the need to withstand prolonged oxidative environment, high speed airflow gentle scouring action, so its heat-resistant material made the demanding requirements. This paper analyzes the domestic and foreign high-temperature resistant materials based on the research carried out ultra-high temperature carbon-based composite materials research, brushing method using slurry introduction of ultra high temperature ceramic components (ZrB2, ZrC, TaC), using precursor infiltration pyrolysis process introduction of the carbon matrix prepared new C/C-ZrB2 (ZrC, TaC) ultra-high temperature composites were investigated precursor species, crosslinking, dipping, puncture and other process parameters on the composite material structure and properties. Using furan resins, phenolic resins, bitumen as a carbon source to study the crosslinking or impregnation process right C/C-ZrB2 composite structures and properties. Furan resin used as a carbon source, impregnation - Crosslinked - Preparation C/C-ZrB2 composite cracking process, the resin cross-linking process in volume expansion and shrinkage cracking process, resulting in poor bonding between layers, and ultimately affect the overall performance composite materials; impregnation cracking process directly after the composite material high density, mechanical properties and good oxidation resistance. Selected phenolic resin with high carbon residue as a carbon source, impregnated - Crosslinked - cracking process composite materials prepared C/C-ZrB2 high density, which can significantly improve the mechanical, anti-oxidation and ablation resistance; while the use of cracking process directly after dipping the composite material of low density, opening rate, corresponding mechanical, anti-oxidation, anti-erosion properties are poor. Respectively, and the molten bitumen impregnated with bitumen solution prepared C/C-ZrB2 composite material, the use of asphalt composites prepared solution of lower density, mechanics, antioxidant and anti-erosion performance is poor; molten asphalt composites prepared better overall performance However, melt impregnation process requires high pressure equipment, high cost, limit the application of the asphalt. In summary, the phenolic resin is a suitable precursor PIP process and impregnation - Crosslinked - cracking process produced the best performance composite materials. Study of high-temperature resistant ceramic powder content on C/C-ZrB2, C / C-ZrC, C / C-TaC composite structures and properties. With ZrB2 content increases, the density of composite materials prepared C/C-ZrB2 increased ablation rate decreased first and then increased, brushing ZrB2 volume content of 10% slurry prepared ZB10 composite material has a more excellent overall properties, bending strength of 250.37MPa, fracture toughness of 13.84MPa · m1 / 2; after 1200 ℃ 30min oxidation rate of 90.65% mass retention, strength retention rate of 85.14%; ablated by oxyacetylene flame 60s quality assessment of ablation rate 0.01802g / s, linear ablation rate 0.0122mm / s. With the increasing content of ZrC, C / C-ZrC composites become increasingly serious phenomenon during the expansion, opening rate increases, anti-oxidation, ablation resistance decreased significantly, brushing ZrC volume content of 15% slurry preparation The ZC15 optimum overall performance composite materials, the flexural strength 217.54MPa, fracture toughness 12.00MPa · m1 / 2; 30min after 1200 ℃ oxidation rate reached 90.91 percent retention quality, strength retention rate of 82.04%; mass ablation rate was 0.01827 g / s, linear ablation rate 0.0193mm / s. With TaC content increases, the prepared C / C-TaC composite density increases, caused by changes in density of the composite mechanical properties and ablation resistance were first increased and then decreased, brushing TaC volume content of 15 % of the slurry prepared in better overall performance composites TC15, the bending strength 260.99MPa, fracture toughness of 13.21MPa · m1 / 2; after 1200 ℃ 30min oxidation rate of 92.12% mass retention, strength retention rate of 75.03%; mass burn erosion rate 0.02510g / s, linear ablation rate 0.0290mm / s. Studied the puncture process on the properties of composite materials. Puncture technique can improve C/C-ZrB2 (TaC, ZrC) composite density, reduced opening rate; enhanced interlaminar shear strength; reduce speed airflow erosion, improve the anti-erosion ability. Compared with non-puncture samples, C/C-ZrB2 composite ablation rate from 0.0135mm / s down to 0.0075mm / s.
