CARBON FIBER WOVEN FABRIC FOR REINFORCEMENT AND WET PREPREG USING THE WOVEN FABRIC, AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a carbon fiber woven fabric which is used for reinforcement and has a large cover factor, in which the fibers are uniformly dispersed in the longitudinal direction and in the lateral direction, and in which spaces 5 made close to cross points formed by the crossing of carbon fiber warps 1 with carbon fiber wefts 2 are small.;SOLUTION: This carbon fiber woven fabric for reinforcement, comprising carbon fiber yarns 1, 2 and auxiliary yarns 3, 4 is characterized in that the carbon fiber yarns are disposed in the warp direction and in the weft direction in a state that the sinking and floating numbers of the carbon fiber yarns in the warp direction and in the weft direction on the upper side of the woven fabric are the same as those on the lower side of the woven fabric and further that the auxiliary yarns 3, 4 are arranged between the carbon fiber warps and/or the carbon fiber wefts and have a woven tissue in which the auxiliary yarns 3, 4 are crossed in the sinking and floating relation different from that of the adjacent carbon fiber yarns.;COPYRIGHT: (C)2002,JPO
