Abstract

PURPOSE:To obtain a tubular structure deflected in any direction by a method wherein a weft is twined round a core body having a bent form or a flexible core body, which is bent, and a group of warps and at the same time the feeding speeds of the warps are relatively changed among themselves. CONSTITUTION:Warps 1, 1', 1'', 1''' and another series of groups are shifted through a ring 4 along a core body 6 upward while repeating up and down movements relative to adjoining warps in order for the weft 2 to intersect and twine round groups of the warps. In this case, the shape of the core body 6, round which the weft 2 is twined, is not simple straight column but bent in an direction in the course to its tip. By shifting a woven body in the direction directing to the tip of the inflect core body 6 after the weft 2 intersect and twine round groups of the warps, the shifting amount of the warps locating at the outer side of the inflect part is rendered to be larger than that of the warps locating at the inner side of the inflect portion, resulting in enabling to manufacture an inflect structure B.

る。A hollow columnar woven structure formed by using reinforcing fibers as warp and weft yarns and winding the weft yarns and warp yarns while appropriately interlacing them is useful as a structure for producing a tubular fiber-reinforced composite material. This structure has the highest reinforcing effect in the axial direction of the columnar structure from the direction in which the reinforcing fiber threads are arranged. This type has a large resistance to compression from the side surfaces of the columnar structure, and its mechanical properties are very high. From this point of view, composite material moldings obtained by using fabric hollow structures as reinforcements and impregnating and curing matrix resins are widely used as high-performance tubular products.

) intertwine with each thread of the warp thread group to form a woven-like structure as shown in FIG. In this way, the intersecting complex made up of the surface layer of the core (3) near the ring (4) is pulled upward one after another, so the weft threads intersect with the warp threads one after another to form a new structure, and the hollow It becomes columnar.

討した結果本発明を完成したのである。Once the shape of the construct is determined, that shape is fixed, so its strength development is extremely good, but on the other hand, it is extremely difficult to change the shape freely like a braid. . Therefore, the present inventors removed such defects and created a material that matched the shape of the final composite material.
A hollow columnar structure that has the shape of a reinforcing structure in advance.For example, a hollow columnar reinforcing structure that is useful when used in a curved shape such as a racket or badminton frame, or a bent axle body of various vehicle bodies such as a bicycle. As a result of studying how to obtain this, the present invention was completed.

あらゆる方向に変曲した管状構造体が得られる。To create the bent tubular reinforcement structure of the present invention,
For example, if we take a circularly bent tubular reinforcing structure as an example,
Since the length of the warp threads forming the tubular shape is longer as the outer circumference approaches the outer side of the circle compared to the inner side of the circle, the amount of warp threads supplied is increased. The gist of the present invention is to sequentially intertwine the weft threads with the warp threads while carrying out such operations, and by performing these operations appropriately, a tubular structure that is curved in any direction other than circularly can be obtained.

によっても作成可能である。A specific example of the method and apparatus for producing the above-mentioned curved tubular structure is shown in FIGS. 4 and 5. First, Fig. 4 shows an example of a method and apparatus for manufacturing a hollow bending tubular structure.
"), (1"') A series of other groups move up and down next to each other, moving upwards on the core body through the ring (4), and at the position of the ring (4), the weft thread (2) or the vertical thread is The mechanism for interlacing and winding the yarn group is the same as in Figures 2 and 3, but in Figure 4, the shape of the core around which the weft yarn (2) is wound is not simply columnar, but has a shape at its tip. In the process of reaching it, it is inflected in a certain direction. After the weft thread (2) intersects and winds around the warp thread group, the tissue body is moved in the direction toward which the tip of the bent core body faces, so that the warp thread is on the outside compared to the warp thread on the inside that is bent in the figure. Those have a large amount of movement of the warp threads,
As a result, a curved structure 13 can be manufactured. in this case,
How to match the desired shape is determined by the shape design of the core body (6), and if the shape of the core body (6) is changed during weaving, it is possible to create not only a circular shape but also a wavy shape (such as two different shapes). It is also possible to create a tubular body with an inflection in the direction.
Even if the core body (6) is fixed, it can also be created by changing its orientation.

置を沿わせると、一層織成が円滑になされる。In Fig. 5, the core body around which the weft threads are wound is not fixed, but the core body (7) is formed by aligning it with the composite material molding in advance, and the warp threads are placed along the core body (7), and the weft threads ( 2) is twisted and wound around the warp yarn group, and at the same time the core body (7) moves while passing through the ring (4). In this method, a bent tubular molded product (B') can be obtained most easily by fitting the core (7) to the final molded product. On the other hand, as described above, by using a flexible core as the core (7), the weft yarn (
The objective can be achieved by bending the core (7) at the intersecting winding point of 2) (a position close to the ring (4)). In this case, if the ring (4) is placed along the direction in which the core body (7) bends, weaving will be made more smoothly.
