Zusammenfassung:PROBLEM TO BE SOLVED: To obtain the subject sheet which has an excellent workability and resin impregnation and is useful for repair and reinforcement of concrete structures by arranging a plurality of carbon fiber yarns having a loop strength over a specific value in parallel. SOLUTION: A plurality of carbon fiber yarns having a loop strength of >=1,000N per 0.9mm cross section according to JIS L 1013 are arranged in parallel to form carbon fiber sheets of unidirectional or bidirectional woven fabric. These sheets has reduced fluffs on their surface and reduced filament breakage on the sheet surface, gives no unpleasant irritating feeling on the construction operation and occurs less fluffs on the impregnation rolling.
