Abstract
PURPOSE: To obtain an additive laminated sheet having an adhesive layer in a usual way by a method wherein a plurality of prepreg sheets are laminated and adhesive layers are formed on the outside of the prepreg sheets on the outmost layers, mold releasing layers are laminated on them and heated under pressure and formed.
CONSTITUTION: The base material such as paper, cloth, etc. is impregnated with varnish such as phenol resin, epoxy resin, etc. and dried to obtain a plurality of laminated prepreg sheets 1. At this time one side of each prepreg sheet 1 on the outmost layers is coated with adhesives to provide an adhesive layer 2, this layer 2 is laminated on other prepreg sheet 1 so that the layer can come outside, in addition mold releasing layers 3 (such as mold releasing paper) are laminated outside the adhesive layers 2. Multilayer substance obtained are heated, pressed and formed to obtain a laminated sheet.
EFFECT: After a laminated sheet is formed, it need not be coated with adhesives or need not use a transfer sheet.
