To provide a method for manufacturing a lightweight, high-strength and high-rigidity laminated sheet and easily manufacture a honeycomb laminated sheet of curved surface shape.
The method for manufacturing a laminated sheet comprises the following process steps of laminating cores 10 comprising fibrous reinforcing materials 2 and 4, thermosetting resin films 6 and 8 and a fiber and lapping a bag 12 on the them to seal the peripheral edge of the bag 12 airtightly with a mold. After that, the cores 10 are compressed by discharging the air between the bag 12 and the mold and the fibrous reinforcing materials 2 and 4 and the cores 10 are impregnated with the thermally molten thermosetting resin film 6. Then, the cores 10 are restored to their original shape by feeding air between the bag 12 and the mold 10 and the resin is thermally set under such a state to manufacture the laminated sheet.
