Problems solved by technology

However, in three-dimensional orthogonal woven fabrics, warp yarns, weft yarns, and binding yarns are in the form of orthogonal straight lines, which cannot meet the above requirements.
Moreover, the warp and weft yarns of multiple layers are bound by binding yarns, and the structure is not compact enough. When the size of the three-dimensional orthogonal woven fabric used is small, the warp yarns and weft yarns are easy to shift or slip off

Embodiment 1

[0031] Design and manufacture a three-dimensional woven composite material with a plain weave structure on the surface and an orthogonal structure on the inner and bottom layers

[0032] 1. There are seven layers of warp and weft yarns in the three-dimensional woven fabric. The warp yarns on the top layer are copper stranded wires, and the warp and weft yarns and binding yarns of the remaining layers are all glass fibers.

[0033] 2. Select the warp and weft yarns of the surface layer of the three-dimensional woven fabric as the plain structure layer, and the other layers as the orthogonal structure layer.

[0034] 3. Weaving three-dimensional woven composite material preforms.

[0035] First, pass the odd-numbered yarns and even-numbered yarns of the first layer of warp yarns (ie copper strands) through the heald holes of the two heald frames respectively. The warp threads of the remaining layers directly pass through the heald frame according to certain rules, without passi...

[0040] Embedding structural health detection devices into 3D woven composites

[0041] According to the design requirements, the optical fiber is embedded in the surface layer of the 20cm-long three-dimensional woven composite material with the corresponding curvature

[0042] 1. Design the three-dimensional fabric with seven layers of warp yarns, select glass fiber as the warp and weft yarns and binding yarns of each layer, and select the thickness of the weft yarns according to the curvature requirements of the optical fiber. In this example, the warp and weft yarn density is 2400tex, and the binding yarn is 400tex;

[0043] 2. Weaving 3D woven composite material preforms

[0044] At first, select five layers of warp yarns, 200 in each layer, change the 100th warp yarn in the first layer of warp yarns into optical fibers and pass through the heald holes. The warp threads of the remaining layers directly pass through the heald frame according to certain rules, without passin...

Abstract

The inventions relates to a manufacturing method for three-dimensional textile having orthogonal structure and plain weave structure, comprising the steps of threading the odd yarns in the longitude yarns through a harness wire hole of one harness frame, threading even yarns through a harness wire hole of another harness frame, interweaving the two harness frames up and down in order to acquire the plain weave structure, respectively threading the odd yarns and the even yarns of binding yarns through a harness wire hole of another two harness frames, interweaving the two harness frames up and down in order to acquire the orthogonal structure of the longitude and latitude yarns of the orthogonal structure layer of the three-dimensional textile, and then integrating the longitude and latitude yarns of the plain weave structure and the yarns of the orthogonal structure layer via vertical binding yarns in order to acquire the three-dimensional textile having orthogonal structure and plain weave structure. The method of the invention is simple and is fit for commercial process. The acquired textile has excellent integrality and interlayer cutting property, meeting the demand for the embedding form of intelligent fiber.

Description

technical field [0001] The invention belongs to the field of preparation of three-dimensional woven fabrics, in particular to a preparation method of three-dimensional woven fabrics with orthogonal structure and plain weave structure. Background technique [0002] One of the important uses of 3D orthogonal woven fabrics is as a reinforcement for 3D woven composites. The mechanical properties along the thickness direction of the three-dimensional woven composite material are significantly improved due to the introduction of fibers along the thickness direction. The "ACT Program" formulated by NASA develops advanced composite materials, making woven composite materials more widely used in large civil aviation airliners. The development of three-dimensional woven composite materials not only improves the shear performance of the material layer, but also improves the strength and toughness in the thickness direction, and has the effect of anti-delamination. [0003] However, t...
