Summary:PROBLEM TO BE SOLVED: To provide a reinforcing fiber sheet for reinforcement of a floor panel, a wall surface or the like of a bridge, a road, a lighthouse, a chimney, a building and the like, favorable in resin impregnation properties, high in proof strength of a resin impregnation sheet and favorable in workability and work efficiency at construction.SOLUTION: In a fiber sheet for reinforcement comprising a textile, a fiber composite of poly(p-phenylene terephthalamide) which is prepared by impregnating a skeleton of a poly(p-phenylene terephthalamide) fiber having the moisture content adjusted to 15-200 wt.% with a curable epoxy compound and a curing agent according to need is used as a warp and/or weft of the sheet. Besides, the fiber composite of poly(p-phenylene terephthalamide) which is prepared by impregnating the above fiber skeleton with a compatibilizer comprising oligooxyalkylene having an alkyl group or an alkenyl group at both terminals, of 0.1-10.0 wt.% as a total amount with the curable epoxy compound is used as the warp and/or weft.SELECTED DRAWING: None 【課題】橋梁、道路、灯台、煙突、建物等の建造物の床盤や壁面などの補強をする為に、糸密度が高い織編物に対する樹脂含浸性が良好で、樹脂含浸シートの耐力が高く、施工時の作業性や作業効率の良い補強用繊維シートを提供。【解決手段】織編物からなる補強用繊維シートであって、前記繊維シートのたて糸及び／又はよこ糸として、水分率１５〜２００重量％に調整されたポリパラフェニレンテレフタルアミド繊維骨格内に、硬化性エポキシ化合物及び必要に応じて硬化剤を、浸透・含浸させてなるポリパラフェニレンテレフタルアミド繊維複合体を用いた補強用繊維シート。更に、前記繊維骨格内に両端末にアルキル基又はアルケニル基を有するオリゴオキシアルキレンからなる相溶化剤を、硬化性エポキシ化合物との合計量として、０．１〜１０．０重量％浸透・含浸させてなるポリパラフェニレンテレフタルアミド繊維複合体を用いた、補強用繊維シート。【選択図】なし
