認められる。Problems to be Solved by the Invention However, the fiber structure for reinforced composite material described in the above-mentioned known literature has dimensional stability or morphological stability, as inferred from the manufacturing method and the like disclosed in the publication. Poor and low fiber volume density. That is, the fiber structures described in JP-B-51-14624 and JP-B-57-17990 have a large number of yarns arranged in parallel along the longitudinal direction of the structural material. Since the width direction yarns and the vertical direction yarns are arranged to form a rectangular parallelepiped fiber structure, a large number of yarn ends are exposed over the entire lengthwise end face of the fiber structure. . For this reason, the yarns arranged near the end face easily fall out, and the volume density of the fiber yarns is low, so that the dimensional stability is insufficient. Further, JP-A-57-133242 discloses that a conical fiber structure is formed by continuously laminating circular woven fabrics, but delamination occurs in this fiber structure. May occur. On the other hand, Japanese Patent Laid-Open Nos. 59-71457 and 5
9-47464 discloses a cylindrical or columnar fiber structure, but the former exposes the cut ends of many yarns on the upper and lower end faces, thereby improving the dimensional stability and morphological stability. In addition, the latter has a large restriction on the arrangement direction and the number of yarns so that the latter is limited to the columnar structure, which is practical in order to improve the design flexibility and productivity. Difficulty is recognized.

と形崩れする恐れもあり、十分とは云えなかった。A conventional fibrous structure in which a first yarn and a second yarn are alternately laminated at right angles and sewn together with a third yarn is disclosed in JP-A-57-176232. As is well known, since the first and second yarns of the fiber structure are disjointed one by one in each layer, the yarn is easily pulled out, the morphological stability is poor, and the fiber structure is hard to be densified. It could not be said to be sufficient, because there is a risk that it will lose its shape when tightened with the thread of No. 3.
