PURPOSE: To obtain three-dimensional woven fabric having a small amount of deformation in a slant direction as composite material aggregate, comprising a warp layer, a vertical yarn layer perpendicular to the warp layer and a bias yarn layer arranged slantingly to the warp layer in a plane parallel to the warp layer.
CONSTITUTION: Vertical yarns are arranged in a state perpendicular to a warp layer composed of several warps in the thickness direction of woven fabric and bias yarns are laid in a sheetlike state in a longer direction of the woven fabric, mutually symmetrically slanted in a pair of two sheets in a plane parallel to the warp layer. The above-mentioned bias yarns are turned up in the midst of the whole width of the woven fabric so that thickness of the woven fabric is changed in the width direction to give three-dimensional woven fabric.
