PURPOSE: To obtain three-dimensional woven fabric useful for binding member having improved fastness to external force, especially compression load by weaving warp and bias yarn in such a way that the outer periphery of a solid member arranged at the end of three-dimensional woven fabric is wound with the warp and the bias yarn.
CONSTITUTION: Part of warp extending in the longer direction of the three- dimensional woven fabric and part of bias yarn mutually asymmetrically arranged slantingly in the longer direction of woven fabric in a plane parallel to the warp layer are woven in a wound state on the outer periphery of metal bushing positioned in the end of three-dimensional woven fabric. When the three-dimensional woven fabric is connected as a composite material comprising a resin a matrix through a bolt or a pin, tensile strength loaded to metal bushing is transmitted and dispersed the warp and the bias yarn to secure strength of the connecting part. An amount of the three-dimensional woven fabric deformed in the slant direction of the composite material is lessened by the existence of the bias yarn and the three-dimensional woven fabric maintains sufficient fastness to compression load.
