The Ministry of the Invention and others previously proposed a grid-like porous structural member in Japanese Patent Application Laid-open No. 1Q55-87541. This structure is made by impregnating and solidifying only each of the above-mentioned strands of a three-dimensional organization consisting of strands in three directions that burn directly with each other, and forming a three-dimensional lattice shape between each strand (with two voids). Therefore, it can be effectively used, for example, as structural parts for civil engineering and construction, aircraft or ships, and lightweight panels.

However, although the structure having the above structure has excellent resistance to stress, compression, tension, bending, etc., when it is formed into a column or beam shape, the strength against torsion is not necessarily sufficient. I can't say it's a thing.

The present invention aims to provide a column-shaped or beam-shaped lightweight composite part side having sufficient strength against various external forces such as compression, tension, bending, and screwing. A form of profiteering is organized by arranging reinforcing striations that are inclined in both left and right directions around a three-dimensional organization consisting of striations in three mutually orthogonal directions: vertical, horizontal, and vertical. By impregnating and solidifying a matrix, the contacting portions of each filament are connected and fixed with gaps provided between the vertical, horizontal and vertical filaments.

Figures 2 and 6 A and B are a front view and lines 1t-n and i■-■ of the embodiments of the present invention, respectively. A cross-sectional view is shown. These composite members use a three-dimensional structure organized by warp yarns z6, weft yarns By winding the reinforcing wire in a spiral shape in both left and right directions, profiteering is achieved. Second
Figures A and B show the case where a three-dimensional structure is woven by simply orthogonally intersecting each of the warp threads Z, weft threads X, and vertical threads Y. On the other hand, this shows a case where the weft yarns X and the vertical yarns Y are intertwined in a structure similar to that of plain weave.

In addition, the spiral thread W arranged around the three-dimensional tissue is
Thread-like or fiber bundle-like material may be spirally wound around the three-dimensional structure at a substantially constant pitch, but prepreg, etc., in which a large number of fibers are arranged in a planar state in an oriented state, may be used to wrap each fiber in the form of a spiral. The threads may be wound in a spiral manner, and furthermore, these spiral threads may be integrated by weaving them into the periphery of the three-dimensional tissue.

Other mineral additives can also be used. When using a synthetic resin as this matrix, for example, it is sufficient to immerse the above-mentioned profiteer in a resin liquid in a dipping tank, take it out, let the resin flow down and defoam, and then harden the resin. As a result, it is possible to obtain a three-dimensional lattice-like composite member in which there are large gaps between the warp threads Z1, weft threads X, and vertical threads Y. It is also possible to use a method in which the excess resin liquid is removed by placing the profiteer immersed in the resin liquid on a centrifugal force-acting knife, and furthermore, the base material is constructed using a filament impregnated with a matrix in advance, 1) At the same time as hardening the glue, the contact portions between the filaments can be connected and fixed.
