Embodiment 1

[0035] Embodiment 1: Using the automatic opening preparation method and device of the fiber layered three-dimensional fabric of the present invention to weave a plate-shaped fabric. The fabric size is 100 mm in length, 20 mm in width, and 2.0 mm in thickness.

[0036] The process design is as follows: the fiber adopts 190Tex quartz fiber; the fabric structure is shallow cross-bending; 2 warp yarns, 4 weft yarns; 4 layers of warp yarns, 16 rows of warp yarns; the warp yarn density is 8.0 yarns / cm, and the weft yarn density is 2.0 yarns / cm; All warp yarns participate in weaving.

[0037] The specific process implementation steps are described as follows:

[0038] 1) passing the warp yarns in the warp let-off system sequentially through the heddles 14 as the warp yarns 10 in the first row of yarns;

[0039] 2) After step 1) is completed, the warp yarns in the let-off system are sequentially passed through the heddles 15 as the warp yarns 11 in the first row of yarns;

[0040] ...

Embodiment 2

[0046] Embodiment 2: Fabrics with special-shaped cross-sections Take fabrics with I-shaped cross-sections as an example. The I-shaped fabric is woven by using the automatic opening preparation method and device of the fiber layered three-dimensional fabric of the present invention. The size of the fabric is 100mm in length, H-shaped section height H=30mm, width B=30mm, and wall thickness δ=10.0mm.

[0047] The process design is as follows: the fiber is made of 12K carbon fiber; the fabric structure is orthogonal three-way; 2 1 strand, 1 strand of normal yarn; cloth yarn is 24 rows, 21 layers; participate in weaving warp yarn 14 layers (21 layers of middle ribs), 24 rows of warp yarns (8 rows of middle ribs); warp yarn density is 8.0 threads / cm, weft yarn density is 4.0 roots / cm.

[0048] The specific process implementation steps are described as follows:

[0049] 1) if Figure 5As shown, the warp yarns in the let-off system are sequentially passed through the heddles 14 as...

Abstract

The invention discloses a yarn distribution method of fiber layer connected fabric. Single-eye heddles are adopted for yarn distribution, heddle eyes of the single-eye heddle are in one-to-one correspondence with each warp of the fabric; during yarn distribution, warp 1 in the first column of warp corresponds to heddle 1 in the first group of single-eye heddles; warp 2 in the first column of warpcorresponds to heddle 2 in the first group of single-eye heddles; ...; after yarn distribution is completed for the first column, the corresponding method of adjacent one column of warp and heddle isthe same as that of the first column; according to the method, other warp is distributed with the same method; the single-eye heddles are arranged in a rectangular manner to form a heddle mechanism, one end of each single-eye heddle is connected with a heddle lifting mechanism above the heddle mechanism, and the other end is connected with a return spring at the lower end; the warp is guided by awarp let-off system one by one, penetrates through the heddle eyes of the corresponding single-eye heddles one by one and sequentially penetrates through reed dent gaps of reeds in a whole column manner. The problems of small opening height, low weaving efficiency, poor structure designability and the like caused by traditional multi-eye heddle yarn distribution manners are solved.

Description

technical field [0001] The invention relates to a method for laying yarns of fiber layered fabrics, belonging to the technical field of three-dimensional fabrics. Background technique [0002] As a reinforced matrix of composite materials, three-dimensional fabrics have many advantages such as light weight, high strength, and excellent mechanical properties, and are widely used in the field of aerospace; as a reinforced matrix of composite materials, three-dimensional fabrics are developing in the direction of various types of structures and diverse shapes. . [0003] The three-dimensional weaving process described in the Chinese patent application CN1570234 uses multi-eye healds to form multi-layer openings at one time. More, the overall size of the loom is larger, and the level of mechanization is lower. [0004] At present, three-dimensional fabric warp yarn usually adopts multi-eye healds (see figure 2 ), the warp yarns are arranged in a matrix in the heald eyes of th...
