Weaving method of three-dimensional T-shaped tubular woven fabrics formed integrally

Abstract

The invention discloses a weaving method of three-dimensional T-shaped tubular woven fabrics formedintegrally. The weaving method of the three-dimensional T-shaped tubular woven fabrics formed integrally comprises the following the steps: (1) designing an overall pattern; (2) designing a pipe regional fabric structure; (3) designing a contour line regional organizational structure; (4) designing a stitching regional organizational structure outside the pipe; (5) designing the shape of a contour line; (6) utilizing a core line extraction method; and (7) adopting the design of NedgraphicsJacquard Computer aided design (CAD), wherein the NedgrahiscJacquard CAD comprises assemblies of NedGraphicsTexcelle2008, LoomEditor, ProductCreator and Weave Editor, designing and outputting the contour line and the organizational structure of fabrics, inputting the contour line and the organizational structure into a source electronic jacquard loom to be woven after a jc5 format file is output. The weaving method of the three-dimensional T-shaped tubular woven fabrics formed integrally can weave a composite material framework of the three-dimensional integrated T-shaped tubular woven fabrics on the electronic jacquard loom which produces ordinary sheet fabrics, and not only can reduce the designing time and is convenient to weave, but also can achieve large-scale local production with low cost.

Description

technical field [0001] The invention relates to a three-dimensional integrally formed T-shaped pipe woven fabric woven on a jacquard loom for producing ordinary sheet-like fabrics, which can be used as a skeleton material for fiber-reinforced composite materials replacing plastic and metal pipes. If it can be combined with an electronic jacquard loom , using the relevant jacquard software system for design, which can effectively reduce the design time and save production costs. Background technique [0002] The composite material of the three-dimensional T-shaped tube integral structure fabric matrix can replace the traditional plastic and metal pipe fittings due to its superior mechanical properties, light weight and corrosion resistance. At present, the possible production methods for weaving T-shaped tubular three-dimensional integral molding structures include short fiber hand lay-up, knitting, braiding and 3D integral weaving.

AI Technical Summary

Problems solved by technology

(1) Short fiber hand lay-up molding method, due to the poor orientation of the fiber, the strength of the fiber cannot be effectively used, so that the strength of the fabric is not enough, and the use is not large; (2) When the 3D overall knitted fabric is used, its coil structure is under load. It can produce large deformation, and it can be made into components with various shapes by taking advantage of its large deformation characteristics. However, composite materials made of this type of matrix are often not rigid enough to be used as load-bearing components, and their uses are limited; (3) Using 3D overall The weaving method is formed, the shape is flexible, almost any shape of fabric can be woven, the strength in one direction is high, and the research results are remarkable. For example, the current satellite truss system is based on braids, but the processing mechanism is complicated, and the equipment must be customized. The manufacturing cost is expensive; (4) The 3D overall woven fabric forming method is adopted. Since the yarn is basically in a straight line in the warp and weft directions, the strength in both directions is high, which is more than 30% stronger than similar woven fabrics. However, this kind of three-dimensional fabric should be woven on a 3D loom, but there is no related equipment at present. Even if the three-dimensional loom is successfully developed, the production cost will remain high; (5) simply use "flattening-weaving-reduction "Multiple-layer tubular woven fabric forming method of the method, although sheet-shaped tubes can be produced, during the stretching process, due to the lack of elongation of the fabric structure, the joints are wrinkled and poorly formed, and cannot be stretched satisfactorily, such as figure 1 shown
