Description of the Related Art Epoxy resin prepregs for producing laminated plates are prepared by impregnating a sheet-like base material such as glass woven cloth with epoxy resin varnish and drying. The drying step is carried out by passing the resin-impregnated base material through a drying furnace equipped with a heating plate, and drying (volatilization of the solvent and curing of the resin) is performed by radiant heat from the heating plate facing the resin-impregnated base material. The hot platen is usually made of stainless steel, and its surface is finished with a satin finish by blasting. In addition, some have begun to study surface treatment such as ceramic coating to improve the radiation characteristics so that far infrared rays are easily generated. Especially, it is suitable for drying epoxy resin-impregnated base materials. Is not suggested.
