ABSTRACT:
A process for producing a laminated panel core made of stainless steel includes the step of preparing a core of the laminated panel by subjecting stainless steel foils to repeated outward and inward foldings in a constant mode in one direction to make a plurality of multi-layered folded sheets of stainless steel. An adhesive is applied to a portion of the surfaces of the folded sheets and a desired number of the multi-layered sheets are laminated. The adhesive causes the sheets to adhere to one another in the areas of application of the adhesive. The laminate is sliced in a plane perpendicular to the plane generally defined by each of the multi-layered sheets into an appropriate small thickness and is extended and deformed in a plane parallel to the plane in which the laminate is sliced and in the direction of lamination of the sheets. A multi-layered sheet for use in a process for forming laminated panels and a stainless steel foil core for use in a laminated panel are also disclosed.
