Three-dimensional fabric.

摘要

Disclosed is a three-dimensional fabric. The present invention is directed at a three-dimensional fabric for a coupling member, which enhances the strength of a coupling portion of a three-dimensional fabric without increasing the volume the coupling portion, as well as improving the hardness or durability against the tensile loads and compressive loads which would act on the fabric and facilitating prediction of the strength of the coupling portion in the stage of designing the three-dimensional fabric in the case where the fabric is used as a composite that is to be used when coupled to another structural member. The three-dimensional fabric (F) comprises a solid member (1) located at one end portion of the fabric; layers of warp strings (z) arranged to extend in a lengthwise direction of the fabric, layers of bias threads (B) so arranged as to be inclined symmetrical to each other with respect to the lengthwise direction of the fabric within a plane parallel to the layers of warp strings (z), and vertical threads (y) arranged to be perpendicular to the layers of the warp strings (z) and the layers of the bias threads (B) to couple these layers. At least a part of the warp strings (z) and at least a part of the bias threads (B) are wound around the solid member (1).
