Example Embodiment
[0030] Example 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 top warp yarns are copper strands, and the warp and weft yarns and bundled yarns of the remaining layers are glass fiber.
[0033] 2. Select the surface warp and weft of the three-dimensional woven fabric as the plain weave structure layer, and the other layers as the orthogonal structure layer.
[0034] 3. Weaving three-dimensional woven composite material preforms.
[0035] First, the odd-numbered yarns and even-numbered yarns of the first layer of warp yarns (ie, copper twisted wires) are respectively passed through the heald holes of the two heald frames. The warp yarns of the remaining layers pass directly through the heald frame according to a certain rule without passing through the hea...

[0039] Example 2
[0040] Embedding structural health detection devices into three-dimensional woven composite materials
[0041] According to the design requirements, insert the optical fiber into the surface layer of the 20cm three-dimensional woven composite material with the corresponding curvature
[0042] 1. Design three-dimensional fabric warp yarns with seven layers, select glass fiber as each layer of warp and weft yarns and binding yarns. Choose the thickness of weft yarns according to the curvature of the optical fiber. In this example, the warp and weft yarn density is 2400tex, and the binding yarn is 400tex;
[0043] 2. Weaving three-dimensional woven composite material preforms
[0044] First, select five layers of warp yarns, each with 200 yarns, replace the 100th warp yarn of the first layer of warp yarns with optical fibers and pass through the heald holes. The warp yarns of the remaining layers pass directly through the heald frame according to a certain rule without ...
