Embodiment 1
[0056] The basic organization is 2 / 2 warp flattening, the number of fabric layers of the basic organization is six layers, and the binding organization is weft binding, such as Figure 5 As shown, it is a schematic diagram of the weft direction of the basic structure of the weft knot. Use four specifications of carbon fiber multifilaments as weft yarns, namely: 3K, 6K, 9K, and 12K, and number them in turn as A, B, C, and D.
[0057]Two-dimensional loom equipment is used to weave and bind multi-layer three-dimensional fabrics in the basic weaving method, and gradually change the weft yarn density, gradually change the number of weft lapped yarns, and gradually change the number of weft yarns interwoven with warp lapped yarns The three methods are combined to gradually change the thickness of the fabric to obtain a three-dimensional woven fabric with variable thickness.

[0063] The basic organization is 2 / 2 warp flattening, the number of fabric layers of the basic organization is six layers, and the binding organization is self-knotting, such as Figure 9 As shown, it is a schematic diagram of the basic structure of self-bonding in the weft direction. Use glass fiber multifilaments of four specifications as weft yarns, which are respectively: 200, 400, 600, and 800, and they are numbered A', B', C', D' in turn.
[0064] Two-dimensional loom equipment is used to weave and bind multi-layer three-dimensional fabrics in the basic weaving method, and gradually change the weft yarn density, gradually change the number of weft lapped yarns, and gradually change the number of weft yarns interwoven with warp lapped yarns The three methods are combined to gradually change the thickness of the fabric to obtain a three-dimensional woven fabric with variable thickness.

Abstract
The invention provides a forming method of various-thickness three-dimensional woven fabric. The forming method is characterized by comprising the following steps of: adopting two-dimensional weaving machine equipment; on the basis of basic structure, adopting a bonding mode to weave and bond multilayered three-dimensional fabric, changing the thickness of the fabric gradually, and obtaining the various-thickness three-dimensional woven fabric. Compared with the prior art, the forming method has the following beneficial effects that the various-thickness fabric is formed by one step, and the integrity and the stability of the structure of the fabric are improved; when the thickness of the fabric is changed, the basic structure is not changed, and the surface appearance of the fabric of the fabric is not changed; the change range of the thickness of the fabric can be set according to the use needs, the change is flexible, and the designability is high; and the fabric can be weaved on the conventional two-dimensional weaving machine, the production and the processing of products are convenient and the cost is in the easily-acceptable range.
Description
technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a forming method of a three-dimensional woven fabric with variable thickness. Background technique [0002] The structural feature of three-dimensional woven is that the warp and weft yarn bundles are interlaced or arranged at 90 degrees in the plane, which provides the in-plane performance of the composite material, and the knotted yarn bundles running through the thickness direction of the structure provide the material stability. Stability, this structural feature makes it have good performance in tensile compression, impact resistance and high-rise shear strength, and is widely used in industrial profiles in aerospace, construction, fishery, sports, military and other fields. [0003] Common three-dimensional woven fabrics are mostly flat plates with a single size and uniform structure, but in some special environments, fabrics with continuously changing cross-se...
