Embodiment 1

[0028] Example 1: The fabric adopts a new structure combining a three-dimensional four-way structure and a 2.5D shallow cross-bending structure.

[0029] refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , the three-dimensional fabric of the new structure of the present invention takes 3K fiber as a 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 one, and the number of strands is 250, and then they are woven into the fabric to reach the designed fabric size. Weave another piece of fabric to complete the three-dimensional and four-way structure part of the new stru...

Embodiment 2

[0031] Example 2: The fabric adopts a new structure combining a 2.5D shallow cross-bending structure and a three-dimensional five-directional structure.

[0032] refer to figure 2 , Figure 6 , Figure 7 , the new structure of the present invention three-dimensional fabric 3K fiber one fiber as a raw material, weaving 100mm * 100mm * 20mm flat fabric as an example, first according to the 2.5D shallow cross-bending structure forming process to complete the weaving of 2.5D shallow cross-bending structure in the fabric, weaving Fabric size 100mm×50mm×20mm, reserve warp yarn, one fiber, 90mm long, 250 pieces.

[0033] According to the design requirements, the formed 2.5D shallow cross-bending structure fabric is fixed, and then the reserved fiber in the 2.5D shallow cross-bending structure is used as the weaving yarn, and part of the weaving yarn is added or directly woven according to the volume density of the fabric. For example, if the volume content is 45%, it is necessary...

Abstract

The utility model relates to a new structure three-dimensional woolen fabric and weaving method thereof. The novel structure three-dimensional fabric comprises a three-dimensional and multi-directional structure and a 2.5D shallow bending structure. The three-dimensional and multi-directional structure is in a structure with three dimensions and more than four directions. The key technique of the novel structure three-dimensional woolen fabric is that fabric between the two structures winds with each other so that continual weaving of fabric within the woolen fabric can be achieved. The novel structure three-dimensional woolen fabric can not only firstly weave from the three-dimensional structure and then weave from the 2.5D structure, but also firstly weave from the 2.5D structure and then weave from the three-dimensional structure. The novel structure three-dimensional woolen fabric has the advantages of being high in forming process reliability, being convenient and easy to operate, being complex in fiber orientation, being high in design of fiber volume content, and being numerous in the continuation of fabric. A novel method of utilizing three-dimensional woolen fabric as reinforcement material for manufacturing composite material of complex bearing components is provided.

Description

technical field [0001] The invention relates to a three-dimensional fabric with a new structure and a weaving method thereof. The three-dimensional fabric is composed of a three-dimensional multi-directional structure and a 2.5D structure, and belongs to the technical field of three-dimensional fabric weaving. Background technique [0002] Mh 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 high-tech fields such as aviation and aerospace, and have good develop...
