Preparation method of ceramic matrix composite light lattice structure
The invention relates to a preparation method of a ceramic matrix composite light lattice structure, and aims to solve the technical problems that fiber bundles between an upper layer plate and a lower layer plate are discontinuous, anisotropy exists in performance and material performance is lost due to the fact that fiber cloth is adopted for preparing middle connection in the preparation of an existing ceramic matrix composite light lattice structure. The method comprises the following steps: 1, obtaining a semi-densification upper pressing plate and a semi-densification lower pressing plate; 2, sewing holes and wiring grooves are machined, and a primary upper pressing plate and a primary lower pressing plate are obtained; 3, obtaining a fiber rope preform; 4, continuously sewing the primary upper pressing plate and the primary lower pressing plate by adopting a fiber rope prefabricated body to obtain a primary ceramic matrix composite light lattice structure; and 5, after densification, carrying out surface treatment to obtain the final ceramic matrix composite light lattice structure.
