Beschreibung
Zusammenfassung:A structure. The structure includes a stack of two or more sheets. Successive sheets in each pair of successive sheets of the stack are adhesively coupled to each other by an adhesive layer consisting of a removable adhesive that is removable if heated to an elevated temperature at which the removable adhesive melts. The removable adhesive is also disposed on top and bottom surfaces of the stack. The removable adhesive consists of a liquid while adhesively coupling the successive sheets to each other. A first surface of a first layer coupled with the removable adhesive to a first surface of the stack. A first surface of a second layer is coupled with the removable adhesive to a second surface of the stack. The first and second layers are adapted to prevent burr formation in a hole subsequently drilled through the stack.
