    Abstract: PURPOSE:To strip mold-releasing sheets easily from an FRP molding by a method wherein the mixture of semi-hardened thermosetting resin and reinforcing fibers are carried between two belt-type mold-releasing sheets and soft materials are inserted between the mold releasing sheets at both ends or stuck to the mold releasing sheets there. CONSTITUTION:In the sheet material used for molding fiber reinforced plastics, a mixture 3 of semihardened thermosetting resin and reinforcing fibers are carried between two belt-type mold-releasing sheets 1, 2. Soft materials 4, 5 in the form of a belt or string are inserted in the lengthwise direction of those sheets between said mold releasing sheets 1, 2 at both their ends. Said soft materials 4, 5 prevent the mixture 3 from flowing out from between the mold releasing sheets 1, 2. In this method, it is possible to strip the mold releasing sheets easily in FRP molding.
