PREPREG SHEET, METHOD FOR PRODUCING PREPREG SHEET, LAMINATED SHEET, AND METHOD FOR REPAIRING OR REINFORCING CONCRETE
To provide a prepreg sheet or the like which can improve the strength of a concrete structure after curing of the sheet.SOLUTION: One embodiment of the present invention is a prepreg sheet for use in repairing or reinforcing concrete. The prepreg sheet comprises a fiber substrate impregnated with a photocurable composition. The photocurable composition comprises a radical polymerizable compound (A) and a photoradical generator (B) and has a thixotropy index TI of 2 or more as measured at 25°C.SELECTED DRAWING: Figure 1
【課題】シート硬化後のコンクリート構造物の強度を向上させることができるプリプレグシート等を提供すること。【解決手段】本発明の一態様によれば、コンクリートの補修又は補強に用いられるプリプレグシートが提供される。このプリプレグシートは、繊維基材に光硬化性組成物を含浸させてなるものである。光硬化性組成物は、ラジカル重合性化合物（Ａ）と、光ラジカル発生剤（Ｂ）とを含み、かつ、２５℃で測定したチキソトロピーインデックスＴＩが２以上である。【選択図】図１
