Embodiment Construction

[0052] Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.

[0053] In the weaving device of the ribbon-shaped fiber bundle fabric of the present embodiment, the ribbon-shaped fiber bundle having a substantially uniform width (expanded width / expanded thickness: 100 or more) with respect to the thickness is preliminarily processed as a ribbon-shaped fiber bundle. , for example, a carbon fiber bundle with an expanded thickness of 0.05 mm and an expanded width of 18 mm (the original fiber before the expansion process) can be used, for example, with an epoxy resin sizing agent slightly bonded to each other in parallel to 12,000 carbon fibers of 7 μm. Beam thickness is 0.1mm, width is 6.1mm).

[0054] This ribbon-shaped fiber bundle is used as the warp T and the weft F to weave a fabric to provide a fabric reinforcement for a carbon fiber-reinforced composite material.

[0055] Next, each constituent member of the weaving ...

Abstract

The present invention provides a weaving device for a ribbon-shaped fiber bundle fabric capable of maintaining a good state of the ribbon-shaped fiber bundle. The weaving device consists of a weft insertion device that inserts the weft yarn (F) into the warp opening area formed by the heddle in a tensioned state, and a moving device that maintains the weft yarn (F) in a tensioned state and moves parallel to the front of the fabric. constitute. The weft inserting device has a rapier mechanism of a rapier loom (or a gripper mechanism of a projectile loom). The rapier mechanism (or projectile mechanism) utilizes the moving device to move parallel to the front of the fabric. On the position close to the rear of the weft yarn (F) picked by the rapier mechanism (or the gripper mechanism of the projectile loom), the yarn guide bar (40) of the warp knitting machine is configured, and the yarn guide bar (40) of the warp knitting machine ( 40) and the rapier mechanism (projectile mechanism) are moved in parallel by the moving device.

Description

technical field [0001] The present invention relates to a weaving device and a weaving method for ribbon-shaped fiber bundle fabrics, which can be used to manufacture reinforcements used in fiber-reinforced composite materials such as composite materials with high quality and good productivity by using fiber bundles that have been tape-shaped treated for warp and weft. Fiber ribbon-like fiber bundle fabric. Background technique [0002] As such a fabric weaving device, there is a device disclosed in Patent No. 2983531 (Patent Document 1). [0003] Compared with the following prior art, this device aims to provide a fabric reinforcement material with good surface smoothness and less bending at the intersection of the weaving threads, and is used to directly use ribbon-shaped fiber bundles to weave split fabrics and expand fibers. silk fabric. [0004] Conventionally, as a technique for obtaining an expanded yarn fabric, there has been a method of expanding the fabric by app...
