2. Description of the Related Art Braided sheets formed by laminating and adhering fiber yarns without weaving are used in various fields.
In particular, triaxial fabrics in which the yarns are reinforced fibers are preferred because of their low directional properties, and the range of applications is widened. For a method of manufacturing a triaxial fabric, see JP-B-62-54.
No. 904. The yarn is alternately hooked on the left and right circumferences of the rotating cylinder on the left and right circumferences to form an oblique body of the yarn on the cylinder, and above and below the oblique body in the circumferential direction of the cylinder. A triaxial fabric is produced by laminating the aligned warp groups and peeling and gluing the laminated body sandwiching the upper and lower portions of the oblique body with the warp groups from the cylinder. By arranging the warp group at the intersection of the oblique body, the basic unit formed by the oblique body and the warp group can be an equilateral triangle, and the strength characteristic is less directional and the design is excellent. A framed fabric can be obtained.

[0003] Triaxial fabric is laminated with paper, film, metal foil, etc., and is used as a component to improve tensile strength and tear strength and to suppress elongation.
It is also used as a reinforcement for fiber reinforced plastics. Particularly recently, as a means of seismic reinforcement of concrete structures such as pillars and bridge piers on expressways, carbon fiber is aligned in one direction and made into a sheet form as a reinforcing material, wrapped around the structure and epoxy resin There has been adopted a construction method of reinforcing by hardening. Triaxial fabric is used as a support for the carbon fiber alignment material. If only the carbon fiber aligning material is used, the carbon fibers are disintegrated at the time of winding or cutting, but if the triaxial fabric is laminated as a support, the handling of the aligning material is very good. Triaxial fabric usually has a fiber spacing of several mm to 20 mm
Because the fibers are laminated at relatively coarse intervals, the triaxial shaft is laminated as a support even when cold-setting epoxy resin is applied and impregnated from the top of the aligned body of carbon fibers wound around the structure. The braid does not hinder the impregnation of the epoxy resin. In addition, since the triaxial fabric is laminated, even when the epoxy resin is applied with a brush, it has an effect of suppressing fluff of carbon fibers.

The characteristics required for the triaxial fabric vary depending on the application. However, in the case of the above-mentioned application as a support for a one-way aligned body, the strength member is made of carbon fiber. The frame fabric itself does not require much strength. The triaxial fabric as the support is required to have a small thickness, a small mass, and a high flexibility while maintaining the strength required for the support. The requirement for a thinner thickness is to form a reinforcing layer by winding a carbon fiber aligned body into a concrete structure while impregnating it with two to three layers of resin. Since the layer is richer in resin than other parts, the layer is more likely to be weak in strength than other parts. Therefore, it is preferable that the film be thin as long as it can function as a support. In addition, since the support side is the surface of the reinforcing layer, if the triaxial fabric is thick, the triaxial fabric pattern will emerge clearly on the surface.

[0005] For the same reason that the mass is small, the smaller the ratio of the support in the reinforcing layer, the higher the strength of the entire reinforcing layer. Regarding the flexibility, the less flexible adhesive can be used to adhere or adhere to the drawn body with a small amount of adhesive. Problems such as peeling are less likely to occur. As described above, the triaxial braided fabric currently on the market is composed of two crosswise oblique yarn groups, one above the other.
Since it is sandwiched between the warp groups of layers, it has a shape like a stack of four layers of yarn. Therefore, the thickness tends to be large for the mass, and there is a surface lacking in flexibility because the upper and lower portions are sandwiched between the warp groups and pressed with the adhesive.

Next, a method for manufacturing a three-layer triaxial fabric according to the present invention will be described with reference to FIG. In FIG. 3, a holding warp group 17 in which reinforcing fiber yarns are aligned at intervals is formed, and an oblique yarn group formed on the circumferential surface of the drum cylinder 4 is laminated on one surface of the warp group 17; Further thereon, a warp group 2 of reinforcing fibers which are aligned at intervals and are laminated, and a lamination 1 ′ in which an oblique thread group is sandwiched between the warp groups 2 and 17.
To form The laminate 1 ′ is taken out of the drum cylinder 4 by the impregnation roller 11 and is impregnated in the impregnation tank 12 containing the binder 13. Subsequently, the excess binder is squeezed by the press roller 14 and sent to the drying cylinder 15. Since the drying cylinder 15 is a contact-type heating cylinder, the laminate 1 ′ is dried on one side. Therefore, the binder adhering to the entire laminate migrates to the cylinder contact surface side of the laminate with one-side drying. As a result, in the dried laminate 1 ′, the amount of binder necessary for adhesion exists at the contact between the warp group 2 and the diagonal yarn group, but the contact between the presser warp group 17 and the diagonal yarn group is present. Does not have the amount of binder necessary for bonding.

The binder used in the present invention is not particularly limited as long as it is a dry type, but a type in which a polymer or copolymer such as an acrylate or vinyl acetate is made into an emulsion is preferably used. Since the triaxial fabric of the present invention has the warp group only on one side of the diagonal warp group, the binder adhering rate as a whole can be reduced as compared with the case where the warp group is present on both sides, and as a result, it has flexibility. Triaxial fabric can be used. The adhesion rate of the binder varies depending on the type of the binder and the type of the reinforcing fiber, but is 3 to 25%.
(Weight) is desirable, but particularly preferably 5 to 10
% (Weight). In FIG. 3, the presser warp group 17 is separated by the separation roller 16 and then returned to the warp group supply section of the drum cylinder 4 for reuse. It can also be based on thread newly drawn from In the warp triaxial fabric of the present invention, the intersections of the diagonal yarn groups and the intersections of the warp yarn groups can be made to coincide with each other, or they can be separated. According to the above-described method for manufacturing the diagonal yarn group, since the diagonal yarn group can be formed accurately, the intersection points can be matched or separated by adjusting the alignment position of the warp yarn group 2. can do. If the triaxial fabric requires thinness, it is better to separate the intersection points. In addition, it is better to match them when the design is strongly required. The angle between the diagonal yarn group and the warp yarn of the present invention is preferably around 60 degrees in terms of the balance of characteristics and the appearance, but is not necessarily limited to this, and can be set in the range of 30 to 80 degrees. .

<Example 1> Yarn used Warp Glass fiber yarn ECG150 1/0 Tex count 33.7 Filament diameter 9 μm Oblique yarn Glass fiber yarn ECG150 1/0 Manufacture of triaxial fabric Cloth A glass fiber yarn was used as a group of holding warps. A aligned sheet is formed on a drum cylinder, and oblique threads are
Obliquely at an angle of degree, and the oblique thread pitch is 1
An oblique thread group was formed at 0 mm. Further thereon, the warp yarns were drawn so as to have a yarn pitch of 10 mm, and a warp group was formed and laminated. At this time, the intersections of the diagonal yarn groups were aligned so that the warps did not overlap. This laminate was impregnated with an acrylic emulsion, dried on one side by a cylinder drier, and after drying, the presser warp group and the triaxial fabric were separated to obtain a warped triaxial fabric. The thickness, mass and adhesion rate of the three-layered triaxial fabric obtained in the above were measured, and the tensile strength, adhesive strength and flexibility were further measured. Regarding the measurement method, the thickness, mass, adhesion rate, and tensile strength are in accordance with JIS R 3420 “General Test Methods for Glass Fibers”. The adhesive strength was measured by measuring the transverse direction of the triaxial fabric according to the JIS tensile strength test method for woven fabrics. The flexibility was measured by the Gurley method of JIS L 1096. Table 1 shows the measurement results.

According to the warp triaxial fabric of the present invention, as in the conventional triaxial fabric, the yarns are arranged in three directions, that is, in the warp direction and in both diagonal directions. It is possible to obtain a triaxial fabric that can be reduced in thickness and has high flexibility, while having the advantage of having a small balance in strength. Therefore, when used as a support for a unidirectional alignment material such as carbon fiber, the support layer can be made thinner, and the resin-rich layer in the reinforcing layer can be reduced. Further, even when the support layer is exposed on the surface of the reinforcing layer, the eyes of the braided fabric are hardly conspicuous. Further, since the braided fabric of the present invention has flexibility, when used as a support for the one-way aligning material, problems such as peeling of the braided fabric from the aligning material during reinforcement work are unlikely to occur. .
