MANUFACTURE OF LAMINATED PLATE

摘要

PROBLEM TO BE SOLVED: To shorten the forming period of time of a laminated plate, and manufacture a laminated plate of which the contraction is small even when receiving a heating in a working process after the forming, and which is excellent in dimensional stability. SOLUTION: For this laminated plate, a layer of an epoxy resin prepreg is pinched between end plates, and they are loaded between press platens which are heated to 165 deg.C in advance, and a heat-press-forming is performed. Then, after the completion of the heating, the forming pressure is released at a temperature which is a glass transition temperature of a thermosetting resin constituting the laminated plate, or higher, preferably right after the completion of the heating, and the laminated plate is taken out from the press hot platens, and the end plates are removed.
