The invention discloses a light anti-ablation C/C-ZrC composite material gas vane and a preparation method and application thereof.The preparation method comprises the steps that a carbon/carbon composite material with the density being 0.8-1.4 g/cm < 3 > is machined, and the carbon/carbon composite material gas vane is prepared; embedding the carbon/carbon composite material gas vane by adopting zirconium-copper alloy powder; and carrying out vacuum hot pressing treatment on the sample subjected to embedding treatment to prepare the light anti-ablation C/C-ZrC composite material gas vane. The preparation method is simple, low in cost and free of pollution; compared with a precursor impregnation and pyrolysis process, the process has the advantages that the preparation period is remarkably shortened, and compared with a conventional reaction infiltration process, the process has the advantages that the reaction infiltration temperature is remarkably reduced, the damage to the mechanical properties of the carbon fibers and the gas vane is greatly reduced, and meanwhile, the ablation resistance of the gas vane is remarkably improved.

    本发明公开了一种轻质、抗烧蚀C/C‑ZrC复合材料燃气舵及其制备方法和应用,包括:对密度为0.8~1.4g/cm3的碳/碳复合材料进行机加工,制备得到碳/碳复合材料燃气舵;采用锆铜合金粉末对碳/碳复合材料燃气舵进行包埋;将经包埋处理后的样品进行真空热压处理,制得轻质、抗烧蚀C/C‑ZrC复合材料燃气舵。本发明制备方法简单、成本低、无污染;与先驱体浸渍裂解工艺相比,本工艺显著缩短了制备周期,与常规反应熔渗工艺相比,本工艺显著降低了反应熔渗温度,大大降低了对碳纤维和燃气舵力学性能的损伤,同时显著提升了燃气舵的抗烧蚀性能。
