    The invention relates to the field of high-temperature-resistant wave-absorbing structures, and particularly discloses a functional fiber gradient distribution-based wave-absorbing ceramic wing-rudder component which sequentially comprises a bearing core layer, a bottom layer, a wave-absorbing layer and a surface layer from inside to outside; the bearing core layer is made of a continuous carbon fiber reinforced ceramic matrix composite material or a continuous low-resistivity silicon carbide fiber reinforced ceramic matrix composite material, the bottom layer and the surface layer are made of a high-resistivity silicon carbide fiber reinforced ceramic matrix composite material, and the wave absorbing layer is made of a single-layer silicon carbide fiber plain cloth reinforced ceramic matrix composite material. The ceramic matrix of each layer of composite material is the same and is one of silicon carbide, silicon-oxygen-carbon, silicon-carbon-nitrogen, silicon-boron-nitrogen, boron nitride or silicon-boron-carbon-nitrogen. The invention further discloses a preparation method of the wave-absorbing ceramic wing-rudder component. The wave-absorbing ceramic wing-rudder component provided by the invention has the integrated functions of high bearing capacity, ablation resistance, strong heat protection, broadband wave absorption and the like, and the survival and penetration capabilities of a new-generation aircraft can be remarkably improved.
