Embodiment 1

[0030] Embodiment 1: The fabric adopts a new structure combining a three-dimensional four-way structure and an orthogonal three-way structure.

[0031] refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , the three-dimensional fabric of the new structure of the present invention takes 3K fiber one fiber as raw material, weaves 100mm * 100mm * 20mm flat fabric as an example, first adopts four-step three-dimensional weaving process, first weaves a section of 100mm * 50mm * 20mm fabric, according to 2.5D shallow The warp length of cross-bending structure requires fiber reserve weaving. When the fiber moves to the right side of the fabric (set as the reserved fiber side), the length of the reserved fiber is greater than 60mm, the number of strands is 1, and the number of strands is 250, and then the strands are woven into the fabric to reach the designed fabric size. Weave another piece of fabric to complete the three-dimensional and fo...

Embodiment 2

[0035] Embodiment 2: The fabric adopts a new structure combining an orthogonal three-way structure and a three-dimensional five-way structure.

[0036] refer to figure 2 , Figure 8 , Figure 9 , Figure 10 , the three-dimensional fabric of the new structure of the present invention uses 3K fiber as a raw material, and weaves a 100mm×100mm×20mm flat fabric as an example. According to the design requirements, weave a 100mm×50mm×20mm orthogonal three-way structure fabric, and arrange 2mm×2mm steel needles For the matrix, first implant Y-direction fibers, then implant X-direction fibers, reserve X-direction fibers or Y-direction fibers according to the overall size of the fabric, one fiber, 90mm long, 25 fibers, which is a fiber layer. According to the process design requirements, the thickness of the fabric contributed by each fiber layer is determined, and the pressure molding is carried out. Repeat the above operations to complete the fiber weaving layer by layer. After ...

Abstract

The invention relates to a new-structure three-dimensional fabric and its knitting method. The three-dimensional fabric is formed through the combination of a three-dimensional multi-way structure and a quadrature three-way structure, and the continuous knitting of fibers in the fabric is realized through the mutual fiber interknitting between the two structures. The knitting method comprises the following steps: carrying out three-dimensional four-way structure knitting, and simultaneously reserving a plurality of fibers on a side surface; and carrying out quadrature three-way structure knitting to reserve one-way fibers in the quadrature three-way structure to complete the knitting of the multi-structure three-dimensional fabric. The molding technology of the three-dimensional fabric has the advantages of high reliability, convenience, easy implementation, complex fiber orientation, strong fiber volume content designability, and continuous fibers, and is a way for solving three-dimensional fabric reinforcement materials for complex bearing member composite materials.

Description

technical field [0001] The invention relates to a three-dimensional fabric with a new structure and a weaving method. The three-dimensional fabric is composed of a three-dimensional multi-directional structure and an orthogonal three-directional structure, that is, the fabric contains two unit cell structures, and belongs to the technical field of three-dimensional fabric weaving. Background technique [0002] High-performance fibers are continuously arranged and entangled in multiple directions in three-dimensional space, and the formed fiber fabric is called a three-dimensional fabric, which is used as a reinforcement to make advanced composite materials. The shape, structure and quality of the reinforcement of the composite material basically determine the performance of the composite material. The performance of the reinforcement mainly depends on the fiber orientation. Composite materials with three-dimensional fabrics as reinforcements have been successfully used in h...
