Publication No. 42 discloses that two or more woven fabrics made of reinforcing fibers are held together in part by binding yarns or stitching yarns of the reinforcing fibers, and other parts can be expanded into two or more fabrics. It is disclosed that the materials are laminated in this manner.

題があった。(Problems to be Solved by the Invention) The method described in Japanese Patent Application Laid-open No. 58-87042 involves laminating a plurality of woven fabrics made of reinforcing fibers and integrating them with binding yarn or stitching yarn. Therefore, the total number of layers of fabric is always equal in the expanded part and the integrated part,
This cannot be differentiated, which limits its uses, and since they are integrated with stitch threads, the number of man-hours increases and productivity decreases. There was a problem with the weft thread being cut.

Because each layer of fabric is thin, and the warp and weft yarns are woven by bending each other, it is a crimp fabric that stretches easily and cannot take full advantage of the yarn strength, which limits its uses. It had been.

By using a conventional multi-layer loom with or without strings, the thickness of the non-separable part separated into upper and lower two layers, the non-separable part, and the joint part adjacent to these can be made thicker, and the thickness can be adjusted to an arbitrary thickness. This allows for three-dimensional molding fabrics to be obtained in one step, and there is no need for stitching using a sewing machine or the like.
In addition, the present invention provides a method for manufacturing a fabric for three-dimensional forming, which allows the yarn used to fully demonstrate its strength.

ける。(Means for solving the problem) A multi-layered fabric having a non-separable part and a non-separable part separated into two upper and lower parts in at least a part of the width direction, and the remaining part forming an integral joint part. In weaving, the core warp yarn and warp yarn are arranged in each of the non-separable parts, non-separable parts and joint parts, and the upper half of the joint part and the non-separable part are placed in the upper weft insertion device using a multilayer loom. Then, the lower half of the joint and the non-separable part are woven using the lower weft inserting device, and the weft thread is inserted twice or more into each of the non-separable part, the non-separable part and the joint part to make the non-separable part. Tighten each of the weft threads in the separated part, non-separated part, and joined part individually with the warp threads.

In this case, since the core warp yarn is taut, the upper and lower weft yarns of the straight core warp yarn are overlapped in parallel, and the double or more weft yarns that overlap above and below are tightened by the warp yarn, and this tightening causes the core warp yarn to , the weft and warp threads are integrated.

Since the weft is inserted by a device, the upper layer portion and the lower layer portion are not connected by the weft threads, but only by the tightening warp threads at the joint. Therefore, if the upper and lower separating parts are located at the ends in the width direction, no matter what kind of tissue is selected for the upper and lower layer parts, the upper and lower separating parts will not be connected at the ears and will be separated. be done.

Either ether ketone fiber or polyester fiber may be used. In addition, so-called prepreg yarns in which these fibers are pre-impregnated with resin can also be used.

Insert the weft thread 3-4 of the first row (fourth row in total) using the shirt handle of the lower string, and then raise the third core warp thread 1 from the top to create the weft thread 3-5 for the fifth row in total. , the fourth core warp yarn l from the top is raised, and only the other tightened warp yarn 2b of the non-separable part B and the other tightened warp thread 2c of the joined part C are lowered, making a total of 6 steps. Insert the weft threads 3-6 into the wefts. Next, replace the positions of the two sets of warp threads 2b, 2b in the non-separable part B and the two sets of warp threads 2c, 2c in the joint part C, and insert the weft threads 3-6 from the bottom. Insert the weft yarn 3-7 in the row, and then lower the core warp yarn 1, tightened warp yarns 2b, and 2a in order to create the weft yarn 3-8, 3-9.
．． 3-10.3-11.3-12 are inserted horizontally. In addition, in FIGS. 1 to 3, the total number of weft threads is indicated by "r3", and the numbers indicating the order of weft insertion are omitted. Furthermore, it goes without saying that punching is required for each width insertion described above. The obtained three-dimensional molding fabric is expanded into an H-shaped cross section (see FIG. 5) by expanding the left and right non-separable portions A and B, and is used as a composite material reinforcing fabric.

The non-separable portion, the non-separable portion, and the joint portion are each connected by tightening warp threads, so that delamination does not occur. Then, the L layer part and the lower layer part can be inserted horizontally using separate shuttle bolts, and the thickness of the non-separable part, the non-separable part and the joint part can be set to the desired structure, number of laminated layers, thickness, and density, respectively. The loom used may be a conventional multilayer loom, either spun or unbraided, and can be efficiently produced in a wide range of sizes.
