Abstract: Described herein is a structure of a motor-vehicle door including a multi-thickness metal sheet pressed and shaped to define: a hinge area configured for fastening one or more hinges for connection to the body of a motor vehicle; a panel area configured for receiving an upholstery-trim element for the door; and a frame area configured for receiving a window of the door. The above multi-thickness metal sheet has a first thickness in said hinge area, a second thickness in said panel area, and a third thickness in said frame area.

Abstract: Described herein is a method for rolling metal sheets of variable thickness. The method makes it possible to impress, during rolling, any distribution of areas of increased thickness within a figure corresponding to the plane development of a motor-vehicle component prior to the pressing operation. Impression of the desired distribution of areas of increased thickness envisages simultaneous impression, during rolling, of a further distribution of areas of increased thickness, or compensation areas.

Abstract: A component of a vehicle structure is obtained by a hot forming operation on a hybrid panel having a sheet element of light alloy and a sheet of plastic material. The hybrid panel is hot formed by pressing it against a forming surface of a mould element by a pressurized gas or by a second mould element. Following this operation, the hybrid panel assumes a configuration corresponding to the forming surface, whereas the light alloy sheet element and the plastic material sheet constituting the hybrid panel adhere to each other following softening by heat of the plastic material. Before the hot forming step, a surface of said light alloy sheet element which must contact the plastic material sheet is subjected to a roughening treatment, thereby defining surface asperities between which the plastic material of the plastic material sheet is inserted when it is softened by heat.
