[0003] Patent 2016104037625 discloses a three-dimensional fabric with a combination of honeycomb holes and its weaving method. This method needs to weave a three-dimensional fabric with a hole structure first. After the three-dimensional fabric is successfully woven, a mold is inserted into the holes of the three-dimensional fabric for overall molding. The process is compared. Complex, so it is necessary to design a weaving method that is directly introduced into the mold for integral sewing into a three-dimensional honeycomb fabric

Embodiment 1
[0036] Embodiment 1 A kind of preparation method of integrally stitched and formed honeycomb three-dimensional fabric
[0037] Taking the honeycomb three-dimensional fabric with regular hexagonal holes as an example, according to the overall size of the overall stitched honeycomb three-dimensional fabric, determine the side length of the mold with a regular hexagonal cross-section, the number of molds required; the tissue structure of the stitched cloth, The length and width of the single-layer cloth, the total number of stitched cloths, and the total length of the yarn used for stitching. Technical indicators: ①The density in the warp direction is 4-10 roots / cm; the density in the weft direction is 4-10 roots / cm; the thickness of a single layer is ≥0.05mm;
[0038] The concrete implementation steps of preparation method:
[0039] (1) Lay the suture cloth, and lay one piece on the top and bottom of each mold. The laying order of the suture cloth and the mold from top to botto...

Abstract
The invention discloses an integrally stitched three-dimensional honeycomb fabric and a preparation method thereof. The method introduces the concept of "putting into a mold - integrally stitched into shape", puts a mold in the middle of the layered fabric and fixes the position, and uses sewing equipment for overall stitching . The composite material made of this three-dimensional fabric has many excellent properties, such as good pressure resistance, stable structure, good heat insulation performance, good designability, and overcomes the shortcomings of low interlayer strength and easy impact damage of layered structure composite materials. . The biggest difference between the three-dimensional fabric as the base material of the honeycomb plate and the general fabric is that it has multiple layers of thickness and can be made into various forms.
Description
technical field [0001] The invention belongs to the field of fiber-reinforced composite materials, and in particular relates to an integrally stitched honeycomb three-dimensional fabric and a preparation method thereof. Background technique [0002] With the comprehensive and excellent performance of three-dimensional fabrics being continuously developed by everyone, three-dimensional fabrics have attracted the attention of relevant research and development institutions around the world, such as DIMA company in Italy, Mitsubishi consortium in Japan, major universities in my country (Donghua University, Tianjin Industrial Co., Ltd. University, Jiangnan University, etc.) have successively started the development of three-dimensional fabrics: either to improve the quality of the finished product, or to optimize the process, or to reduce the cost. [0003] Patent 2016104037625 discloses a three-dimensional fabric with a combination of honeycomb holes and its weaving method. This ...
