Abstract: A method for manufacturing a semifinished product or component is disclosed in which a metal support embodied as a split strip is covered with at least one prepreg containing a thermally cross-linkable thermosetting matrix with endless fibers, the thermosetting matrix of the prepreg is pre-cross-linked by means of heating, and the metal support covered with the pre-cross-linked prepreg is formed into a semifinished product or component by means of roll forming. In order to enable plastic deformation in fiber-reinforced regions of the metal support, it is proposed that during the pre-cross-linking of the thermosetting matrix of the prepreg, its matrix is transferred into a viscosity state that is higher than its minimum viscosity and prior to reaching its gel point, the prepreg is formed together with the metal support.

Abstract: A method for producing partially hardened steel components in which a blank composed of a hardenable sheet steel is subjected to a temperature increase and shaped into a component; the component is transferred to a tool in which the heated component is cooled and thus quench hardened; during the heating of the blank or component in order to achieve the temperature increase to a temperature required for the hardening in regions that are to have a lower hardness and/or higher ductility, cooling elements are spaced apart from the surface by a small gap; the cooling element is dimensioned so that the thermal energy acting on the region that remains ductile flows through the component into the cooling element, characterized in that in order to space the cooling element apart from the component, micro-nubs or knobs are used, which are distributed over the area of the cooling element.

Abstract: A method for producing a shaped part from an aluminum sheet that includes an aluminum alloy, in particular an aluminum alloy of the 5000 series. The method includes introducing at least one aluminum sheet in a forming tool and cold-forming the aluminum sheet in the forming tool, and heating the cold-formed aluminum sheet at least once at least in some regions and at least once further metal forming the aluminum sheet. In order to create advantageous conditions for the method, it is proposed for the heated aluminum sheet to be subjected to the further metal forming step even before a temperature has been reached which the aluminum sheet has during the cold forming thereof.

Abstract: The invention relates to a method for producing quenched components consisting of sheet steel, comprising the following steps: a) shaped parts are formed from sheet steel; b) the end of the shaped part is cut and the sheet steel is optionally punched or provided with a desired hole pattern prior to, during, or after the forming of the shaped part; c) at least some sections of the shaped part are subsequently heated to a temperature that permits the steel material to austenitize; and d) the component is then transferred to a quenching die, where it is subjected to a quenching process, during which the component is cooled and thus quenched by the contact of the quenching die with some sections of the component and the compression of said sections. The invention is characterized in that the component is supported by the quenching die in the vicinity of the positive radii and that some sections of said component are clamped in a secure manner without distortion in the vicinity of the cut edges.

During the heating of the blank or component, absorption masses rest against and/or are spaced with a small gap apart from regions that are intended to have a lower hardness and/or higher ductility; with regard to its expansion and thickness, its thermal conductivity, and its thermal capacity and/or with regard to its emissivity, the absorption mass is dimensioned so that the thermal energy acting on the component in the region to remain ductile flows through the component into the absorption mass.
