Problems solved by technology

[0008] In order to solve the existing honeycomb fabrics woven by integral stitching, integral weaving or shuttle loom weaving, the preparation process is complicated, the fabric strength is poor, the cross-sectional shape of the fabric is single, the number of fabric layers is small, the overall continuous weaving is not possible, and there is no high cost. In order to solve problems such as the panel layer of strength, the present invention provides a kind of three-dimensional sandwich structure fabric and its weaving method

Abstract

The invention discloses a three-dimensional sandwich structure fabric and a weaving method thereof. The three-dimensional sandwich structure fabric comprises an upper panel layer formed by interweaving at least one layer of upper layer warp yarns and weft yarns, a lower panel layer formed by interweaving at least one layer of lower layer warp yarns and weft yarns, and a core layer formed by interweaving at least one layer of intermediate layer warp yarns and weft yarns; and the upper panel layer and the lower panel layer are connected with the core layer by layer connection structures, and thefabric is formed by integral continuous weaving. The three-dimensional sandwich structure fabric provided by the invention has the advantages of diversified tissue structures, large fabric size control range, diversified cross-sectional shapes, strong designability, suitability for continuous weaving and the like; and a fabric composite reinforced material has the characteristics of high specificstrength, high specific rigidity, good structural stability, fatigue resistance, vibration resistance, sound and heat insulation and the like, and can be widely applied to the fields of aviation, aerospace, ships, automobiles, buildings and the like.

Description

technical field [0001] The invention relates to the technical field of three-dimensional fabric weaving, in particular to a three-dimensional sandwich structure fabric and a weaving method thereof. Background technique [0002] The sandwich structure is a composite structure composed of more than three layers of materials or structures. It consists of two thin and high-strength panel structures with a thick and light core layer sandwiched between them. This is to meet the requirements of light weight and high strength. A structural form developed. The purpose of adding the core layer is to maintain the distance between the two skin layers, which increases the moment of inertia and bending stiffness of the sandwich skin section. Due to the small specific gravity of the core layer, the sandwich structure made of it can greatly reduce the self-weight of the structure under the same bearing capacity. The sandwich structure has the advantages of high specific strength, high spe...
