There are different lamination processes, depending on the type of materials to be laminated. The materials used in laminates can be the same or different, depending on the processes and the object to be laminated. An example of the type of laminate using different materials would be the application of a layer ofplastic film—the “laminate”—on either side of a sheet ofglass—thelaminatedsubject.
Vehicle windshields are commonly made by laminating a tough plastic film between two layers of glass. This is to prevent shards of glass detaching from the windshield in case it breaks. Plywood is a common example of a laminate using the same material in each layer. Glued and laminated dimensioned timber is used in the construction industry to make wooden beams,Glulam, with sizes larger and stronger than can be obtained from single pieces of wood. Another reason to laminate wooden strips into beams is quality control, as with this method each and every strip can be inspected before it becomes part of a highly stressed component.
Electrical equipment such astransformersandmotorsusually usesteellaminations to form the core ofcoilsused to producemagnetic fields. The thin laminations reduce the loss due toeddy currents.
