REINFORCED FIBER SHEET

PROBLEM TO BE SOLVED: To enhance a developing ratio of a strength, to upgrade operability of a building site execution, and to shorten an executing time by adhering reinforcing fibers arranged in one direction to a support having intersecting pluralities of warps and wefts, and arranging the warps of the support at a specific pitch. SOLUTION: This reinforced fiber sheet is obtained by adhering reinforcing fibers arranged in one direction to a support having intersecting pluralities of warps and wefts. As the fibers, carbon fiber, aramid fiber, glass fiber or the like is used, but preferably the carbon fiber is used. As the support, a plurality of the warps of a reinforcing fiber direction and a plurality of the wefts perpendicular to the warps are arranged normally at a pitch of an equal interval. Intersections of the warps and the wefts are obtained by adhering them with an adhesive or arranging the one fibers of two at the same position and sandwiching the other yarns between the two yarns and twisting it to fix it. The warps of the support are arranged at a pitch of 25 mm or above.
