Field of the Invention The present invention relates to a spread yarn woven fabric, and more particularly to a spread yarn woven fabric which is pre-spread and woven from a band-like fiber bundle having a substantially uniform width with respect to its thickness. In particular, it is useful in the technical field of weaving a woven fabric reinforcing material as a reinforcing material for a fiber-reinforced composite material.

らである。2. Description of the Related Art When molding a fiber-reinforced composite material,
As a reinforcing material, a woven fabric obtained by weaving a reinforcing fiber bundle such as carbon fiber or glass fiber is often used. This is because these fabric reinforcing materials have advantages that they are easy to handle, can reduce the laminating process, and can improve impact resistance by preventing delamination.
【0003】しかし、従来の織物補強材は、経糸と緯糸

イド部分が発生し易くなり信頼性に欠ける面があった。[0003] However, in the conventional woven fabric reinforcement, bending of the fiber bundle at the intersection of the warp and the weft is inevitable, and the mechanical properties inherent in the fiber bundle are likely to be impaired due to stress concentration at the bent portion. was there. In addition, unevenness was generated on the surface due to the bulging of the intersection of the weaving yarns, and when laminated to form a composite material, the uneven distribution of the reinforcing fibers was likely to cause a resin excess portion or a void portion, and there was a surface lacking reliability. .
【0004】一方、炭素繊維束は、その製造工程の都合

しかし、繊維束が太くなるほど、織糸の交差部での屈曲

ことになり、積層複合材料中のボイド等の欠陥が発生し
易くなる傾向がある。On the other hand, the production cost of the carbon fiber bundle decreases as the number of single yarns increases (the fiber bundle becomes thicker) due to the manufacturing process. Therefore, if the woven reinforcing material is woven with a thick reinforcing fiber bundle, an inexpensive reinforcing material can be obtained.
However, the thicker the fiber bundle, the greater the bending at the intersection of the yarns, and the lower the resin impregnation in the fiber bundle, and the easier it is for defects such as voids in the laminated composite material to occur. Tend.

There have been proposed a number of methods for producing a woven fabric reinforcing material for the purpose of providing a woven fabric reinforcing material having less bending at the intersections of the yarns. For example, Japanese Patent Publication No. 2-323832, Japanese Patent Laid-Open No. 4-2
81037, JP-A-8-127959, JP-A-8-127
No. 232135 describes a method of opening a woven fabric by applying a water jet to the surface of the woven fabric. Also, Japanese Patent Publication No. 4-70420, Japanese Patent Laid-Open No. 145556/1995.
Japanese Patent No. 4-24116 describes a method of opening a woven fabric by applying ultrasonic waves in water.
No. 4 describes a method of opening a woven fabric using a rotary drum and water pressure.

った。However, in these conventional methods for producing a fabric reinforcing material, a reinforcing fiber bundle is once woven in a state of a multifilament yarn, and then a high-pressure fluid or ultrasonic waves are applied to the obtained woven fabric. Because the method is a method of opening the fiber bundle forming the woven structure, there is a limit to the opening width, and the opening of the fiber bundle at the intersection of the yarns must be insufficient. Therefore, there is a limit in reducing the degree of weft yarn bending at the intersection and improving the surface smoothness.Furthermore, breakage or misalignment of the single yarn of the fiber bundle is likely to occur due to the injection pressure of the high-pressure fluid or the like. However, there is a problem that the quality of the fiber reinforcing material is deteriorated.

複合材料を簡単に成形することができなかった。Further, the conventional woven fabric reinforcing material has only a weft perpendicular to the warp, and when a fiber reinforced composite material having isotropic properties such as strength is to be formed, it is independent of the weaving direction. There is no other way than to diagonally laminate the fabric reinforcing material itself, and a large-area, high-quality fiber-reinforced composite material cannot be easily formed due to the weaving width.

Since it is formed by directly weaving a thin and flattened band-shaped fiber bundle that has been opened beforehand, the fiber bundle is sufficiently opened even at the intersection of the warp and the weft, and has excellent resin impregnation. ing. In addition, since the fiber bundle is less bent at the intersection and the stress concentration on the bent portion is reduced, the mechanical properties of the fiber bundle can be fully utilized, and the surface smoothness of the woven fabric can be improved. Therefore, even when the composite material is formed by laminating, there is no occurrence of a resin excess portion or a void portion due to uneven distribution of the reinforcing fibers. Further, since the spread fiber woven fabric itself is thinly woven, drape property (property along the shape) which is important when used as a fabric reinforcing material can be remarkably improved.

Also, if the fiber opening process is performed sufficiently thin and wide on the fine fiber bundle in advance, the spread yarn can be used as it is to produce a woven fabric, so that a high-quality woven fabric reinforcing material can be provided at low cost.

The warp group can be fed by the width of the weft while the warp group is held by the holding means 1. Therefore, if a dancer roller as tension adjusting means 7 is arranged between the gripping means 1 and the delivery roll 14 as in the embodiment shown in FIG. It is also possible to open and close the warp group while keeping the position fixed.

With reference to FIGS. 11 to 14, a description will be given of a manufacturing process of the spread yarn fabric of the second embodiment. Note that FIG.
Among through 13, those indicated by reference numeral F 1, F 2 is the cloth fell line of valley folding state of woven strip sliver to be gripped by the gripping means 2 of the front T, by the symbol H 1, H 2 What is indicated is a heald line in a mountain-fold state of the band-shaped fiber bundle T supported by the heald means 3, and what is indicated by reference numerals G 1 and G 2 is the band-shaped fiber to be gripped by the gripping means 1 on the warp bobbin side. It is a holding line in a valley folded state of the bundle T.

である。However, when weaving a woven fabric in which the weft is oblique to the warp, the weaving direction is oblique to the warp direction, and as shown in FIG. T of the cloth fell line F 2 is also oblique with respect to the warp direction. Therefore, as shown in FIGS. 12 and 13, in order to perform the opening operation without giving a twist to the band-shaped fiber bundle T,
Healds line H 2 and gripping line G 2 must also be parallel to the front line F 2 woven by interlinked obliquely to the warp direction, moreover, each aperture operation at the same time heald line H 2 and the gripping line G 2, woven It must reciprocally moved parallel to a direction perpendicular to the front line F 2. If here, heald line H 2 and gripping line G which has interlinked obliquely relative to the warp direction
If 2 is moved in the warp direction in the same manner as in the case of the orthogonal weaving, the belt-like fiber bundle T is geometrically twisted.

に緯入れする。As shown in FIG. 14, the opened yarn woven fabric of this embodiment in which the weft is oblique to the warp first has a pair of grips which are oblique to the warp direction while maintaining a parallel relationship with each other. In a state where the warp groups are gripped at predetermined intervals by the means 1 and 2, the heald means 3 parallel to the grip means is moved up and down, and at the same time, the heald means 3 and one of the grip means 1 are gripped on the cloth fell side. The warp group is slantly opened without imparting a twist to each belt-like fiber bundle T by being parallel-moved and approached in a direction perpendicular to the direction 2, and the weft insertion means 4 inserts the weft into the slant opening into the gripping means. Insert the weft parallel to it.

The parallel transfer is performed to the position of the gripping means 2. Thereafter, the group of warps is closed by the heald means 3 to release the gripping state of the gripping means 1 on the warp bobbin 15 side and the gripping means 2 which has gripped the weave front. The fiber bundle T is sent out by the slant width. Thereafter, the sent warp group is again gripped by the pair of gripping means 1 and 2, and these are repeated to be continuously woven.
