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.

A method for manufacturing a semifinished product or part is disclosed in which a metal support embodied as a metal sheet or blank 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 part by means of deep drawing or stretch deep drawing. 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.
