Producing system and method for mixed-braiding unidirectional fabric

Abstract

The invention relates to a producing system and method for mixed-braiding unidirectional fabric. The system comprises a knit-stitch machine; a compression roller, a yarn sley, a carbon fiber warp rack and a weft laying device are arranged at the left side of the knit-stitch machine successively; a dragging roller, a fabric rack and a glass fiber warp rack are arranged at the right side of the knit-stitch machine successively; and a coiling head and a roller are arranged on the top of the knit-stitch machine. A glass fiber warp yan is led out from the carbon fiber warp rack and is fed into the knit-stitch machine by the roller; a carbon fiber warp yarn is led out from the carbon fiber warp rack and is fed into the knit-stitch machine by the yarn sley and the compression roller; a glass fiber weft yarn is fed into the knit-stitch machine by the weft laying device; and a stitching yarn is led out from the coiling head and is fed into the knit-stitch machine. The knit-stitch machine stitches the glass fiber warp yarn, the carbon fiber warp yarn, the glass fiber weft yarn, and the stitching yarn; a piece of blank cloth after stitching is dragged by the dragging roller into fabric and then the fabric winds around the fabric rack. According to the invention, on the basis of the novel structure, efficient production of the mixed-braiding unidirectional fabric can be realized; and the fabric quality can be guaranteed.

Description

technical field [0001] The invention relates to the technical field related to textile machinery, in particular to a production system and method for mixed knitting unidirectional fabrics. Background technique [0002] In the application of wind turbine blades and automobiles, the requirements for material strength are getting higher and higher, and the performance of some parts of glass fiber fabric products is difficult to meet the requirements. [0003] Carbon fiber and its composite materials have the characteristics of low density, high strength, and high and low temperature resistance. Since the advent of carbon fiber, with the maturity of technology and the decline of cost, the application fields have expanded from aerospace, defense and sports and leisure products to emerging application fields such as reinforced plastics, pressure vessels, building reinforcement, wind power generation, and drilling platforms. [0004] The performance comparison of each fiber is sho...

AI Technical Summary

Problems solved by technology

[0010] And because the carbon fiber is brittle, and the length of the line in the existing production line is relatively large, the carbon fiber is severely worn, which affects the quality of the fabric

As another drawback, the components in the existing production line are not properly positioned, so after a yarn break, the repair takes a long time
