Title:
CORE MATERIAL HAVING ZERO POISSON'S RATIO AND PREPARATION METHOD THEREFOR, AND COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2023/217048
Kind Code:
A1
Abstract:
The present invention provides a core material having a zero Poisson's ratio. The core material is formed by a plurality of cell units of the same type arranged without gaps; each cell unit comprises two first type unit walls, which are arranged opposite each other, and two second type unit walls, which are arranged opposite each other, wherein the two first type unit walls are connected through the two second type unit walls to jointly enclose the cell unit; the first type unit wall and the second type unit wall are both walls shared between adjacent cell units; the first type unit wall is used as a cell wall of the cell unit, and the two first type unit walls are arranged in parallel; and the second type unit wall at least comprises two cell walls, which are connected in sequence, and an included angle is formed between the two cell walls of the second type unit wall which are connected in sequence, so that the second type unit wall is of a bendable structure. The core material has a simple structure and the zero Poisson's ratio. Further provided in the present invention are a preparation method for the core material having a zero Poisson's ratio, and a composite using the core material having a zero Poisson's ratio.
