Abstract
PURPOSE: To mold a lamination sheet which has the reduced unevenness in the thickness of a sheet and no air bubble contained, by a method wherein, when a plurarity of pairs of resin-impregnated base materials are heated for pressurization between two heating plates, a necessary pressure is applied according to an insertion position of the base material.
CONSTITUTION: A required number of resin-impregnated base materials 5, in which resin is impregnated into the base material, are piled up to form a lamination sheet material. A plurality of pairs of said lamination sheet materials, which are piled up through the medium of pannels 4, are inserted between two heating plates 1 for heating and pressurization to form a lamination sheet. When producing said lamination sheet, it is pressurized at a low-pressure when resin of the lamination sheet material at the heating plate side begins to melt, and it is pressurized at a high pressure with the fusion of the lamination sheet materials at the middle. Said procedure permits molding of the improved lamination sheet which has reduced unevenness in the thickness of the sheet, and besides, contains no air bubble.
