Embodiment 1

[0042] This equipment is used to weave a plane three-way fabric (plain basic weave), which is composed of two sets of warp yarn systems y, z and one set of weft yarn system x. The oblique warp yarn is T300-1K carbon fiber, the weft yarn is T300-3K carbon fiber, the angle between the warp and weft yarn is 60°, Px=Pz=25 threads / 10cm, the width and fabric length of the woven flat three-way fabric are respectively 600mm, 20000mm. Five cylindrical needles are arranged in a single needle row board, the distance between the horizontal yarn hanging guide rails is 600mm, the distance between the cylindrical needles in the needle row board is 100mm, and the required number of horizontal needle rows is 7. The length of the weaving platform is 6000mm, and the distance between longitudinal cylindrical needles is 170mm. Longitudinal yarn hanging guide cylinder needle row board completes 24 cycles. The number of oblique warp yarns required is 5,700, and the number of weft yarns required is 5...

Abstract

The invention relates to weaving equipment for planar tri-axial fabric and a method. The equipment can be used for weaving a planar tri-axial fabric basic texture structure, a double-plain structure and other changeable texture structures. The equipment is characterized in that according to the structure parameter requirements of the planar tri-axial fabric, the continuous weaving process with anadjustable inclined yarn angle and an adjustable weaving breadth of the fabric in the length direction can be realized. With the method, weaving procedures can be reduced, and production costs can belowered; the method is simple and wide in fiber application range. When a prefabricated part is produced, thread residue breaking caused by rubbing does not occur easily, the overall performance of the fabric is good, structural stability and uniformity can be improved, and the quality of composite materials can be improved to a certain degree.

Description

technical field [0001] The invention relates to a plane three-way fabric weaving equipment and method, in particular to a high-performance fiber plane three-way fabric weaving equipment and a fabric weaving method, belonging to the technical field of fabric weaving. Background technique [0002] The planar three-way fabric has the characteristics of isotropy, and it has good tensile and shear properties when it is stressed in any direction. The good structural stability and uniform bearing capacity in any direction of the planar three-way fabric have attracted attention in more and more industries. For example, it is used as a reinforced skeleton material in automobile airbags, tire cords, reinforcement of cracks in buildings, and radome in the aerospace field. In recent years, developed countries have focused on the application of planar three-way fabrics in the design of ultra-thin, ultra-light, and extensible spatial structures, which put forward higher requirements for ...
