Carbon-glass one-step hybrid weaving technology and device

Abstract

The invention discloses a carbon-glass one-step hybrid weaving technology and device. The technology comprises the steps that carbon fiber is unwound through a constant tension creel, subjected to yarn collection through a yarn collection rack and subjected to thread-used fiber spread by a fiber spread device, the carbon fiber, glass fiber spun yarn which is conveyed by a weft laying device in the same direction and glass fiber which is conveyed in the other direction synchronously enter a multi-axial warp knitting machine to be woven into carbon-glass hybrid fabric, and then rolling is conducted. According to the carbon-glass one-step hybrid weaving technology and device, a novel technology route is provided, controlled thread-used fiber spread which is synchronous with weaving is adopted, one-step hybrid weaving is achieved, the production cost and labor cost are lowered, the labor intensity of workers is lowered, the waste is reduced, and the energy is greatly saved.

Description

technical field [0001] The invention relates to a carbon-glass one-step mixed weaving process and device. Background technique [0002] Carbon glass blended fabric combines the advantages of carbon fiber and glass fiber, so it is widely used in industrial manufacturing fields such as wind power generation blades. When weaving carbon fiber and glass fiber blended fabrics, it is generally necessary to spread the carbon fibers first, so that the carbon fiber bundles are flatter, thinner and more uniformly arranged, so that the performance of the fabric is better. [0003] The existing process is to spread the fiber off-line and warp it on the pan head, and then weave the carbon fiber layer and the glass fiber together through a special unwinding device on the multiaxial warp knitting machine. But the shortcomings of this process are also obvious. Due to the requirement of winding and unwinding, the production process route is lengthened and the labor workload is increased. Th...

Problems solved by technology

However, the shortcomings of this process are also obvious. Due to the requirement of winding and unwinding, the production process route is lengthened and the labor workload is increased.

The biggest disadvantage is that due to the diameter of the warping head, the limitation of the door width and the production of the warping machine will cause a lot of waste of raw materials: 1. Due to the limitation of the diameter of the warping head, the length of the carbon fiber warping meter is limited. , the meter length of the carbon-glass mixed fabric is also greatly restricted

2. Every time the pan head is replaced, the carbon fiber layup must be pulled from the unwinding position to the take-up shaft of the multi-axial warp knitting machine, and the width needs to be aligned. In this process, at least the time between the weaving area and the winding is wasted. a meter long

Due to the large waste caused by the requirements of the process, the cost is increased
