  • Process for the production of finished parts
    Patent number: 10632692
    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
