示されている。[Prior art 1. Many warps 2. The skeleton material is a three-dimensional fabric consisting of three types of yarns, the first weft y and the second weft Composite materials with matrix are #1 for rockets, aircraft, automobiles, ships and buildings! It is expected to have a wide range of uses as a Li material. Conventionally, as a method for manufacturing three-dimensional textiles, for example, Japanese Patent Application Laid-Open No. 61-296143
As shown in Figure 18, the publication describes warp threads arranged in multiple layers! A horizontal bar 61 is used to open the layer one by one with a horizontal bar 61, and one continuous weft W is sequentially inserted back and forth into the warp opening, and each time a weft W is inserted into each warp opening, one opening between the warps is inserted. Insert the weft bar 62, move the weft bar 62 m forward to perform weft, and after weft insertion and weft of all layers are completed, tighten the bar 63 by pulling it out to the side and tightening the heald 64. Move up and down to reverse the binding thread S.
and then 1.9 Uj! A method for weaving a three-dimensional &i-type article is disclosed in which the tightening process is repeated by inserting a bar 63 between the binding yarns S and the warp yarns T and tightening the binding yarns S, as shown in FIG.

- Direction, 3D & 1! Composite material using i4I as a skeleton material (4 is expected to be used in a wide range of applications as mentioned above, and is suitable for applications where the cross-sectional shape is other than square, e.g. U-shaped, 1
It is desired to efficiently weave three-dimensional fabrics with irregular cross-sections having character shapes or hollow portions. However, the conventional method cannot produce a three-dimensional fabric with such an irregular cross section. Therefore, when manufacturing a composite material (1) with an irregular cross section using a three-dimensional object as a skeleton material, it is conceivable to first manufacture a block-shaped composite material and then add T to a predetermined shape. There is a problem that not only is it time-consuming, but there is also a lot of wastage of materials.

The warp thread Z of the next row of the second group of warp threads 21 is placed in the - raised position by the upward movement of the heald 5, and the warp thread 10 is moved to the opposite side of the warp thread zKF as shown in FIG. state. At this time, since the other side wall part [warp thread z of pa
The weft is inserted into vS@, which is folded back between the warp threads Z. On the other hand, another second weft X2 is similarly inserted between the rows of the second group of warp yarns on the other side wall portion Fb using another spool (not shown). Then, the heald 5 is moved up one side by F so that the warp spacing []1 is lowered one step at a time, and the second wefts x and x2 are inserted. In this way, the side wall portion Fa,
When weaving Fb, one side wall [? When inserting the second weft X into the warp opening of a, the second group of warp threads forming the other side wall part is held in a position that does not interfere with the insertion of the second LI thread insertion. Even if the spool 10 or the shuttle 9 is moved over the entire width direction of the three-dimensional fabric F, weaving will not be hindered.

端部が多数あっても支障はない。In the above embodiment, the three second wefts x, xi, and x2 were used to weave the side wall parts Pa and Fb, but in this embodiment, only one second weft X was used to weave the second weft from the hollow part. First, a three-dimensional fabric is produced with the second weft X inserted, and then the second weft X inserted into the hollow part is cut and removed.
Target hollow three-dimensional fabric 1? This embodiment differs greatly from the previous embodiment in that it is manufactured. Therefore, in this embodiment, the heald 5 of the warp shedding device 4 does not need to be able to independently open the warps Z of each row of the two groups of warps constituting the opposing side wall portions sandwiching the hollow portion, and The second group is opened all at once for each row, and the warp threads t? The second weft X is sequentially inserted into the M opening. The weft healds 721 to 7c are operated in the same manner as in the embodiment described above, and the first weft yarn y is placed in the position corresponding to the hollow part.
The second weft X inserted into the hollow part is cut and removed after the three-dimensional product is woven, but only the second weft X is inserted into the hollow part. Therefore, the second weft X can be easily removed. In addition, there are many cut ends of the second thread on the inner surface of the hollow part, but since the three-dimensional woven fabric is used in a resin-impregnated state, even if there are many cut ends, there is no problem. do not have.

奏する。[Effect of the invention 1 As detailed above, according to the invention described in the first claim,
It is now possible to efficiently produce three-dimensional fabrics with high density and cylindrical shapes, which are made of threads with components in three directions x, y, and z, and whose cross-sectional shapes are irregular or cylindrical. By impregnating resin in its original form, a lightweight, high-strength, and highly homogeneous composite material using a three-dimensional fabric as a skeleton material can be obtained with minimal finishing processing. or,
In the invention according to the second claim, since the insertion of the second helix yarns X between the rows of the seven groups of warp yarns constituting the mutually opposing 1l11% 1 part of the hollow three-dimensional fabric is performed independently,
The configuration of the second weft insertion device can be simplified. In addition, in the invention described in claim 3, even if the fabric is a hollow three-dimensional fabric, weft insertion can be carried out in the same operation in the hollow part and the part other than the hollow part by conveniently using only one second weft X. This has the excellent effect of increasing the weaving speed of three-dimensional fabrics.
