Abstract:
1. A method for producing a uni-directional carbon fiber woven fabric woven comprising: weaving a carbon fiber strand having a fineness of 400 to 6,000 tex as a warp yarn and an auxiliary fiber having a fineness of ⅕ or less of the carbon fiber strand as a weft yarn to form the uni-directional carbon fiber woven fabric, wherein said weaving of the uni-directional carbon fiber woven fabric includes weaving by an air jet loom in which a heald in a shedding motion has an angle of repose in a range of 0 to 50°; weaving a different weaving structure simultaneously at least in an end that is an opposite side from a weft yarn insertion side of the carbon fiber woven fabric using the weft yarn weaving the carbon fiber woven fabric; and giving a twist to the different weaving structure after cutting the weft yarn between the different weaving structure and the carbon fiber woven fabric to separate the different weaving structure from the carbon fiber woven fabric.
