因する強度低下という問題も派生する。However, all of these known fiber structures for reinforcing structural materials have a low fiber content ratio and have numerous yarn ends on their end surfaces. The fiber structure is exposed in the cut state and is not strong enough (also, because of this, when impregnating with thermosetting resin, pitch, etc., the threads may fall off and the fiber structure may lose its shape, or the fiber structure may lose its shape). In order to remove the parts where collapse occurred, it was necessary to perform cutting after the resin, pitch, etc. had hardened.In addition, machining was required when manufacturing composite material molded products with complex shapes, and This also leads to the problem of reduced strength.

A first endless thread (Yl) is meanderingly arranged in a direction perpendicular to the axial direction of the spacers (2) (2) along...
At the point where the formation of the layer is completed, the meandering direction of the first endless yarn (Yl) is changed, and the meandering direction of the first endless yarn (Yl) is changed in the same manner as described above along the direction parallel to the axial direction of the spacers (2) (2). 1
The endless thread (Yl) is arranged in a meandering manner. The number of stacked layers of the first endless yarn (Yl) is adjusted by considering the compression allowance in advance so as to match the design dimensions of the fibrous structure that is the final product. When the lamination of the first endless yarn (Yl) is completed, the spacers (2), (2), etc. are placed on the obtained laminate of the first endless yarn (Yt). Spacers (2) (2) arranged on the r side of the laminate...

・The first endless yarn (Y-shaped laminate) is tightened from above and below using the pressure member (2') (2°). (Yr) laminate can obtain a preset yarn density and laminate thickness. The laminate of endless yarns (Y, ) is tightened after completing the lamination of the first endless yarn,
It may be carried out at one time, but when forming a thick fibrous structure, it may be carried out several times in the middle of laminating the yarns to cumulatively increase the fiber density. Further, the spacer (2) can have any cross-sectional shape such as a thin plate shape or a rod shape.

最終製品に仕上げられる。When the formation of the laminate made of the first endless yarn (Yl) is completed, the step of inserting the second endless yarn (Y2) is started. That is, after removing the pressure members (2') (2'), the separators (5) are removed one after another, the yarn guide tube (1) is lifted up near the spacer (2) located below, and the 2
The endless yarn (Y2) is bent into a loop shape and hooked on the yarn guide (6), and the loop (L) of the second endless yarn (Y2) thus formed is hooked onto the yarn guide (6). 6), insert it into the inside of the yarn guide tube (1). Next, pull up the yarn guide tube (1) and insert the loop (L) into the first
In this state, remove the yarn guide tube (1), and then insert the third endless yarn (Yl) into the loop (L). Y3)
Insert it as a bar thread. Thereafter, the yarn stack formed from the first endless yarn (Yl) is sequentially tightened by applying a tensile force to the second endless yarn (Y2) and pulling it back downward. The above-mentioned insertion and tightening operations using the second endless yarn (Y2) are repeated for the number of yarn guide tubes (1) to increase the fiber density of the fiber structure to a predetermined level. By sequentially inserting the third endless yarn (Y3) through the loop (L) in this way, the third endless yarn (Y3) is arranged in a meandering manner on the upper surface of the yarn stack. The fibrous structure thus obtained can be finished into a final product as it is or after being impregnated with a thermosetting resin, thermoplastic resin, pitch, etc. according to a conventional method.

For example, an H-shaped body, an H-shaped body, a cylindrical body as illustrated in FIG.
Various types of fiber structures such as truncated cones and tubular bodies with notches can be manufactured.

減らしても必要な設計強度を維持することができる。In the above embodiment, the second endless yarn (Y2) is disposed over the entire area of the fiber structure. Therefore, the loop appears on the upper end surface of the fiber structure, and the thread is inserted through the loop, but in order to further strengthen only a specific direction of the fiber structure, the first endless thread is inserted into the loop. Alternatively, the insertion area of the second endless thread (Y2) may be limited. At this time, it is possible to insert the second endless yarn in a cross shape or diagonal shape into the four surrounding surfaces and inside the fiber structure, as illustrated by the shaded area in FIG. For the portions other than the second endless yarn arranged crosswise or diagonally, it is possible to select whether the first endless yarn is layered or not. This allows the required design strength to be maintained even when the total weight of the fibrous structure is reduced by reducing the amount of yarn.

度低下の防止に対しても大きく寄与し得るものである。By employing the method of the present invention, the fiber structure can be formed into a fa layer to increase its thread density, and since it can be firmly tightened, the morphological stability of the reinforcing base material can be improved. is significantly improved compared to conventional products. Furthermore, in the present invention, it is possible to arrange the threads only in the direction in which the strength of the laminate is required due to the design, and the arrangement of threads is partially omitted in areas where strength is not required. It is also possible. Furthermore, since a fiber structure is formed in which the ends of the fiber threads are not substantially exposed, there is no risk that the threads will fall off and the fiber structure will lose its shape during transportation or impregnation with thermosetting resin, etc. Furthermore, there is no need to cut the core after the resin or pitch has hardened in order to remove the deformed portion. Therefore, the present invention not only makes it possible to freely mold composite materials having complex shapes, but also greatly contributes to preventing strength reduction due to machining.
