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.
