The invention relates to a gradient porous ceramic-based composite material, a product thereof and an additive manufacturing method, belongs to the technical field of additive manufacturing, and solves the problems that a gradient porous ceramic material and a product thereof in the prior art are difficult to give consideration to light weight and high strength, poor in design freedom degree, low in manufacturing efficiency and difficult in process quality control. The gradient porous ceramic-based composite material comprises a ceramic matrix formed by 3D printing and a reinforcing phase, the ceramic matrix comprises n layers of ceramic matrix layers with different material components and/or densities to form a gradient structure, the reinforcement phase comprises W layers of two-dimensional fiber fabrics which are distributed layer by layer in the 3D printing stacking direction, and each layer of two-dimensional fiber fabric is located in the adjacent ceramic matrix layer; in the 3D printing stacking direction, the n ceramic matrix layers and the W two-dimensional fiber fabric layers are stacked layer by layer. The gradient porous ceramic-based composite material formed by 3D printing and the product thereof have the advantages of excellent broadband wave-transparent performance, light weight, high strength and the like, and the degree of freedom of design is large.
