METHOD FOR MANUFACTURING LAMINATED SHEET

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a laminated sheet not generating voids. SOLUTION: In a manufacturing method for obtaining the laminated sheet molded under pressure and heating, hot plates are raised after a vacuum degree reaches 100 Torr or less to start pressurization. There is no restriction in relation to heating and constituent articles can be also inserted in the gap between the hot plates heated to a molding temperature to be held thereto. By drawing a vacuum before the hot plates are closed, air between the constituent articles can be sufficiently removed and the generation of voids is suppressed.
