description | A method of curl control for lamination of a polymer sheet to each side of a core material comprising providing a bottom polymer sheet, bringing said bottom sheet into contact with a heat source, providing said core material, bringing said core material into contact with said bottom polymer sheet while simultaneously applying a binder between said bottom sheet and said core to form a laminate, providing a top polymer sheet, bringing said top sheet into contact with said laminate and while simultaneously applying a binder between said top sheet and said laminate to form a composite wherein each sheet to core modulus ratio is greater than 1 and wherein said composite has a desired curl. |
