Abstract
The invention discloses a lightweight and multi-level orthogonal corrugated core sandwich structure and a preparation method thereof. The multi-level structure comprises a first-level upper panel, a first-level lower panel and a first-level orthogonal corrugated core body arranged between the first-level upper panel and the first-level lower panel. The first-level upper panel, the first-level lower panel and the first-level orthogonal corrugated core body are respectively composed of a second-level upper panel, a second-level lower panel and a second-level core body arranged between the second-level upper panel and the second-level lower panel. The invention also discloses a preparation method of the multi-level structure. Based on the multi-level structure, the occurrence of the elastic buckling phenomenon of the structure is delayed, so that the resistance of the entire multi-level structure to local deformation is improved. A gap, formed based on the orthogonal design of the core layer of the structure, provides a space for the multifunctional design of the structure. Therefore, according to the requirements of engineering applications, functional components can be placed on the structure or sound-absorbing materials or other functional materials can be filled inside the structure. As a result, the multi-functionalization is realized.
