摘要： The present invention relates to a method for manufacturing a product with a spatially structured surface from a semi-finished product, a semi-finished product required for this purpose and a product produced in this way. The method is characterized in that a patterned target bending location is produced in the semi-finished product, and in that the semi-finished product is then subjected to a pressure over its surface, which is dosed in such a way that the pressure causes a plastic deformation of the semi-finished product along the target bending location, so that a product with a spatially structured surface is produced.

摘要： An aerofoil structure with a hollow cavity is manufactured by diffusion bonding and superplastic forming. Outer panels are formed of a first material; a membrane is formed of a second material. Stop-off material is applied to preselected areas on at least one side of the membrane or of one of the panels so as to prevent diffusion bonding between the panels and the membrane at the preselected areas. The panels and the membrane are arranged in a stack and a diffusion bonding process is performed to bond together the first and second panels and the membrane to form an assembly. A superplastic forming process is performed at a forming temperature to expand the assembly to form the aerofoil structure. The forming temperature is selected so that the second material undergoes superplastic deformation at the forming temperature and the first material does not undergo superplastic deformation at the forming temperature.

摘要： A sheet of material is held in a die opposite a forming surface of the die, and gas pressure is applied to both sides of the sheet. The pressure creates a compressive stress in the sheet thickness direction sufficient to cause plastic flow. By maintaining the pressure higher on the side of the sheet opposite to the forming surface, the sheet bends and expands toward the die forming surface. This pressure differential can be increased as necessary to bend the sheet into the crevices which make up the details of the forming surface. The sheet may be heated during forming to lower the compressive stress which is required to cause it to flow plastically.

摘要： A hollow three dimensional metal article is formed by cutting two identical flat metal blanks, forming a hole in one of the blanks and upsetting the metal around the hole to accommodate the head of a threaded hollow stud having a sealing collar without interference when the blanks are in face contact, placing the blanks in face contact while the stud is in place, welding the metal blanks together continuously around the entire perimeter of the superimposed blanks, and forcing liquid under pressure through the hollow stud until a precise preset maximum pressure is reached to inflate the blanks to their final three dimensional form. Optional steps include cutting off the portion of the three dimensional form in which the stud and the opening for the stud are located and welding a standard fitting into the opening thus created and the provision of other portions of the three dimensional object with other attachments and fittings.

摘要： 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.

摘要： A leading edge structure of an aircraft airfoil including an outer skin, a front wall extended in the spanwise direction of the leading edge structure in a front section of the space defined by the outer skin so as to form an anti-icing duct together with a front part of the outer skin, and a plurality of ribs disposed in the space defined by the outer skin so as to form hot air passages. A laminar structure is formed by superposing upper and lower sheets of a superplastic titanium alloy, inserting a pair of core sheets of a superplastic titanium alloy between the upper and the lower sheet, and forming release agent layers in predetermined regions between the sheets. A structure having at least the outer skin, the front wall and ribs is formed by joining together parts of the super-posed sheets corresponding to regions not coated with the release agent layers by diffusion bonding or welding, heating the laminar structure in a forming mold, supplying a superplastic forming gas into spaces between parts of the superposed sheets corresponding to regions coated with the release agent layers to subject the same parts of the superposed sheets to superplastic deformation and to press the upper sheet and the lower sheet against the forming surface of the forming mold.
