Abstract
PURPOSE:To obtain a prepreg which can give a laminated sheet excellent in dimensional stability, low in warp and twist and free of bubbles by molding at a low pressure, by pressing a woven cloth with a nip roll, passing it through a resin solution to adhere the resin solution thereto and drying it. CONSTITUTION:A woven cloth 1 such as a glass cloth surface-treated with a silane coupling agent and wound into a roll is pressed with a nip roll 4 at a pressure of 1-70kg/cm<2> to render it easily impregnatable with a resin solution 2, passed through a resin solution tank 5 filled with a resin solution 2 such as a varnish of a thermosetting resin such as an epoxy resin, a polyester resin or a polyimide resin to adhere the resin to it, passed between, e.g., a pair of rolls to squeeze adherent excessive resin to a specified thickness and led to a drying chamber 3, where it is brought into B stage to obtain a prepreg 6.
