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.

Method for manufacturing a semifinished product or a part made of metal and fiber composite

The invention relates to a method for producing a semi-finished product or component (), in which a hardenable coating () with fiber-reinforced plastic is applied to a metal carrier (), particularly a metal sheet (), and the coated metal carrier () is formed, particularly deep-drawn or bent, in a subsequent step to produce a semi-finished product or component (). According to the invention, for an improved and cost-effective method, the metal carrier () is coated at most only in certain regions and is only subjected to the forming when the coating thereof () has hardened to produce at least a block-resistant surface (), the coated metal carrier () being formed such that the plastic changes in shape follow forming radii () and are produced substantially, preferably exclusively, in the coating-free regions () of the metal carrier.
