Abstract
PURPOSE: To improve the mold releasing property without deteriorating the characteristics inherent in the impregnating resin by a method wherein the base material for an external layer prepreg is formed larger than that of an internal layer prepreg and a specially modified substance is used as the impregnating resin for the external layer prepreg.
CONSTITUTION: First the internal layer prepreg 1 is formed by impregnating the base material such as a craft paper, glass fiber cloth, etc. with epoxy resin and dryed. On the other hand, the base material having a larger shape than that of the internal layer base material and a metal mold 3 for a multistage press is impregnated with the epoxy resin modified by an excellent mold releasing resin such as resol type phenol resin and dried to form the external layer prepreg 2. Then, the external layer prepregs 2 are laminated on both the upper and lower surfaces of a plurality of laminated internal layer prepregs 1 and sandwiched between the molds 3 of the multistage press, molded in heating and under pressure to obtain the laminated board.
EFFECT: The shape of the external layer base material is so large that resin does not attach to the mold through the resin flows out in heating and under pressure.
