Abstract: The invention relates to a process for the production of finished parts made of at least one multilayer, fiber-reinforced, flat semifinished-product structure, comprising the following steps: a) heating of the at least one multilayer, fiber-reinforced, flat semifinished-product structure at ambient pressure to a first temperature Ta, where the at least one multilayer, fiber-reinforced, flat semifinished-product structure comprises at least two mutually superposed polymer layers and the individual polymer layers respectively have fiber-reinforcement and do not have coherent bonding to one another or have only partial coherent bonding to one another, and in the event that at least one of the polymer layers comprises a semicrystalline polymer the first temperature Ta is higher than a melting point Tm of the crystalline polymer in accordance with DIN EN ISO 11357-3:2013-04, and in the event that the at least two polymer layers comprise no semicrystalline polymer the first temperature Ta is higher than a glass transition temperature Tg in accordance with DIN EN ISO 11357-2:2013-09 of a polymer comprised in at least one of the at least two polymer layers, b) pressing of the heated at least one multilayer, fiber-reinforced, flat semifinished-product structure to give a finished part at a second temperature Tb and at a pressure pb of at least 3 bar.

Abstract: The invention relates to a process for the production of multishell composite-material components, comprising the following steps: a) insertion of at least one first component (1) into an injection mold and optionally subjecting the first component (1) to a forming process, b) injection of at least one fixing element (4) onto at least one side (5) of the first component (1), c) insertion of at least one second component (2) into the injection mold and optionally subjecting the second component (2) to a forming process, d) bonding of the first component (1) to the second component (2) by way of the side (5) which has the fixing element (4), where a matrix material (6) is injected through the second component (2) onto and/or into the fixing element (4).
