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 warp yarns and weft yarns, and at least one layer of lower layer warp yarns interwoven with weft yarns. The lower panel layer is formed, and the core layer is interwoven with at least one intermediate layer of warp yarns and weft yarns; the upper and lower panel layers and the core layer are connected by a layered structure, and are formed by continuous weaving as a whole. The three-dimensional sandwich structure fabric of the present invention has the advantages of various organizational structures, large fabric size control range, various cross-sectional shapes, strong designability, and is suitable for continuous weaving. The composite reinforced material with this type of fabric has high specific strength and high specific stiffness. High, good structural stability, fatigue resistance, vibration resistance, sound insulation and heat insulation, etc., can be widely used in aviation, aerospace, ships, automobiles, construction and other fields.

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...
