PROBLEM TO BE SOLVED: To prepare a reinforcing fiber sheet for the mending or reinforcement of a concrete structure such as the pier of a high-level road, bridge or the pillar of a building or the manufacture of a structure such as ship or automobile, easily handleable at the work site, having good impregnation property of a resin in the pasting lamination work, free from the problem of considerable suppression of the cold-setting property of the resin used in conventional lamination work and giving a cured product having sufficient reinforcing effect or mechanical properties. SOLUTION: Reinforcing fiber bundles containing 0.1-15wt.% of a resin are arranged in one direction, heat-weldable fibers are placed perpendicular to the reinforcing fiber bundles interposing 5-150mm gaps between the weldable fibers along the longitudinal direction of the reinforcing bundles and the reinforcing fiber bundles are welded with the weldable fibers. |
