2. Description of the Related Art A large number of warps stretched in a plurality of rows and a plurality of rows, and first and second wefts (vertical yarns) and second wefts woven between the rows and rows of the warp group so as to be orthogonal to the warps, respectively.
A composite material using a three-dimensional woven fabric composed of various kinds of yarn as a skeleton material and a resin or inorganic material as a matrix is expected to be widely used as a structural material for rockets, aircraft, automobiles, ships, and buildings. In order to use this kind of composite material for a wide range of applications, it is necessary to connect each member like a general metal structural material. Conventionally, an example of using for connecting the composite together with the three-dimensional textile and skeletal material is not, as shown in FIG. 1 3 is a laminate formed by laminating a large number of cross-skeletal material and composite material, the composite 60 Metal bushing 6
1 is used to connect the composite materials 60 to each other or to connect the composite material 60 and another structural material 62 with bolts 63 and nuts 64. When connecting a composite material using a three-dimensional fabric as a skeleton material using bolts and nuts or using pins, it is necessary to make a hole in the composite material and fit the metal bushing 61 in the same manner as described above.

However, when a hole 65 for fitting a metal bushing is formed in the composite material, the yarn constituting the fabric F is cut at a portion corresponding to the hole 65 as shown in FIG. Therefore, the strength of the portion corresponding to the portion (particularly the strength against the force in the direction of the arrow) decreases, and in order to increase the strength of this portion, the values of the length L and width W of the portion must be increased. However, there is an inconvenience that the volume surrounding the metal bushing 61 becomes large, which is the same as the laminated composite material. In addition, since drilling is performed after the formation of the composite material, a minute crack or the like is generated depending on the finishing condition of the processing, and there is a problem that fracture due to stress concentration is likely to occur, and it is difficult to predict the strength by design.

Further, if the three-dimensional fabric is composed of yarns (fibers) having only three orthogonal axes of X, Y, and Z, a composite material formed by using the three-dimensional fabric as a skeletal material has a three-dimensional structure. Although it shows sufficient durability against a tensile load, since there is no fiber oblique to the longitudinal direction of the woven fabric, the amount of deformation with respect to a force oblique to the longitudinal direction of the three-dimensional woven fabric increases. Accordingly, the resistance to a compressive load tends to be weaker than that of a tensile load.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. A metal bushing 2 as a solid member is disposed at a predetermined position on the substrate 1 corresponding to the outer diameter shape of a desired three-dimensional fabric, and a number of pins 3 for regulating the arrangement of the yarns are set up at right angles to the surface of the substrate 1. Set up. Then, a warp z, a bias yarn B or a weft x is arranged in the gap between the pins 3 on the substrate 1 to form a warp layer, a bias yarn layer or a weft layer. For example, as shown in FIG.
Are formed in a folded shape along the circumferential direction. The weft layer is formed by, for example, as shown in FIG. 2, the weft yarns x being arranged in a folded manner so as to be orthogonal to the warp z. The yarns continuous with the weft yarn x are arranged in the radial direction of the metal bushing 2 so as to be orthogonal to the warp z around the metal bushing 2. In this case, the weft x and the yarn of the radial component need not necessarily be connected. Also, as shown in FIG. 3, the bias yarn layer is arranged such that the bias yarn B is at 45 ° to the longitudinal direction of the substrate 1.
And the metal bushing 2 is arranged in a folded shape along the circumferential direction. In this case, the portion where the bias yarns B are arranged to cross each other has two layers, whereas the other portion has one layer. In order to form the bias yarn B in two layers in all parts, another bias yarn B is arranged in the state shown in FIG. As a result, a pair of uniform bias yarn layers is formed. FIG. 5 shows a state in which the respective layers are superposed one by one. After the required number of layers are laminated according to the magnitude and direction of the load assumed to be applied to the coupling member, the pin 3 is connected to a vertical thread (not shown).
To form a three-dimensional fabric.

The pin may be any one that can be easily replaced, such as a hollow small-diameter pipe or a solid rod. The three-dimensional fabric manufactured as described above is impregnated with a resin and formed into a composite material. Metal bushing 2
When used in connection with other members at the portion of the above, the load applied to the metal bushing 2 is reliably transmitted to the main body of the three-dimensional fabric via the warp z and the bias yarn B. And
When a compressive load is applied to the metal bushing 2, the bias yarn B shares a force in the direction to endure it, so that it exhibits strong robustness and enhances its function as a connecting member.
In addition, the vertical yarn joined the layers of the warp z, the weft yarn x, and the bias yarn B to prevent delamination, and applied an axial force to the metal bushing 2 or applied a shock at right angles to the three-dimensional fabric layer. It will be the case resistance.

When there is a yarn (radial yarn) that is arranged in a folded manner in the radial direction with respect to the metal bushing 2 as in the three-dimensional fabric of this embodiment, a certain amount of space exists between the metal bushing 2 and the yarn. Clearance is required,
This clearance becomes a resin layer in the composite material. And
If the resin layer is too thick, it can easily be broken.
Or by impregnating the resin with the resin, or removing the metal bushing 2 at the time of thread arrangement, disposing a pin at the outer peripheral position to facilitate the thread arrangement, and replacing the outer peripheral pin and the metal bushing 2 after the thread arrangement is completed. Is also good. Each of the yarns arranged around the metal bushing 2 is
The metal bushing 2 may be provided with a large number of holes through which the radial yarn is folded, and the radial yarn may be passed through the hole in a folded manner so as to be integrated firmly with the metal bushing 2. In this case, the metal bushing 2 used at the time of arranging each yarn is used as it is for the composite material. The plurality of holes are formed in such a shape that a part of the folded radial yarn does not protrude to the inner surface of the metal bushing 2 and the folded part is not damaged.

The present invention is not limited to the above-described embodiment. For example, a pattern in which the warp z is arranged around the metal bushing 2 may be simply formed along the circumferential direction around the metal bushing 2. Figure 6 instead of arranging
As shown in FIG. 7, the arrangement may be such that the inside and outside of the circumference enter and exit. In the case of such an arrangement, the function of uniformly distributing the load of the wound portion over the inner and outer layers and transmitting it to the support portion is increased, and the robustness (durability) is improved.
Further, the warp z and the bias yarn B arranged around the metal bushing 2 are folded back so as to make a half circumference of the metal bushing 2 in the examples so far, but the procedure shown in FIGS. Through the warp z, a part (or the whole) of the warp z is completely wound around the metal bushing 2 or is wound around the entire circumference through the warp z in a procedure as shown in FIGS. It may be. Although not shown in the figure, a part (or all) of the bias yarn B may be wound in the same manner. Such an arrangement has the effect of propagating the load applied to the metal bushing 2, particularly the compressive load in an oblique direction, to the entire support member composed of the three-dimensional fabric, and as a result, the coupling member is particularly effective. It exhibits extremely tough durability against the required compressive load. In such a yarn arrangement, the overlap of the yarn layers around the metal bushing 2 increases, and the thickness of the fabric becomes thicker than in other portions. And the insertion distance of the weft yarn x can be adjusted by stopping at a part of the fabric width.

A pipe is erected on the substrate 1 in place of the pin 3, and after a predetermined number of warp layers, bias yarn layers and weft layers are laminated, a vertical thread is inserted through the pipe without removing the pipe. May also be incorporated into the three-dimensional fabric together. Further, the present invention is applied to a four-axis three-dimensional fabric in which layers constituting three in-plane axes composed of a warp z and a bias yarn B are stacked in layers without using the weft yarn x and are joined by vertical yarns in the thickness direction. May be. In the case of a four-axis three-dimensional fabric, when the warp z and the bias yarn B constituting the three in-plane axes are arranged so as to intersect at an angle of 60 degrees with each other, the fiber filling ratio is lower than that of the five-axis three-dimensional fabric. It is easy to increase the thickness, and the thickness of the bias yarn B can be increased. When the composite material is used, the strength against the oblique force is improved, and the strength against the warp-direction shear compression is increased.

As described in detail above, according to the present invention, the warp and the bias yarn are arranged in the gap between the pins or pipes erected along the outer periphery of the solid member, so that the warp and the bias yarn can be freely arranged around the solid member. Since the yarn can be wound around the solid material, the solid member can be woven into the woven fabric without cutting the yarn, and is resistant to tensile and compressive loads. A three-dimensional fabric suitable as a skeleton material can be easily manufactured.
