Abstract:
1. A method for producing a laminated composite by laminating a polyolefin resin drawn sheet on at least one face of a sheet-form core material having a density of 30 to 300 kg/m 3 , comprising: interposing, between the core material and the drawn sheet, a bonding synthetic resin or rubber having a flow starting temperature lower than the thermal deformation temperature of the core material and the melting point of the drawn sheet; heating the synthetic resin or the rubber to not less than the flow starting temperature and not more than the thermal deformation temperature of the core material and the melting point of the drawn sheet before or after the three materials are stacked into a stack product; and pressing the stack product to apply a compression strain of 0.01 to 10% to the core material at the same time of or after the heating.
