High-temperature-resistant broadband wave-transparent ceramic radome structure and preparation method thereof
The invention discloses a high-temperature-resistant broadband wave-transparent ceramic radome structure and a preparation method thereof. The high-temperature-resistant broadband wave-transparent ceramic radome structure comprises a homogeneous outer layer, a porous layer, a homogeneous inner layer and a homogeneous connecting layer. The high-temperature-resistant broadband wave-transparent ceramic radome structure is integrally formed by adopting a single wave-transparent ceramic material. Uniformly distributed holes are formed in the porous layer, and the homogeneous outer layer, the porouslayer and the homogeneous inner layer form an A sandwich structure to realize broadband wave transmission. According to the invention, the preparation method adopts an ultraviolet light curing 3D printing method for overall preparation; the radome structure meeting different wave transmission requirements is obtained by regulating and controlling the thicknesses of the homogeneous outer layer, the homogeneous inner layer and the porous layer, the diameters of holes and the distances between the holes; and the high-temperature broadband wave-transparent ceramic radome structure provided by theinvention has the advantages of high temperature resistance, broadband wave transparency, high strength, simple structure, good reliability and the like.
