Abstract: A method and a device are provided for consolidating a fiber composite structure with at least one thermoplastic and/or thermoelastic polymer. The fiber composite structure is arranged between two pressing elements of a device for consolidating the fiber composite structure. The pressing elements are pushed toward one another such that the fiber composite structure is pressed therebetween. The fiber composite structure is heated at least into the range of a melting temperature of the at least one polymer. After cooling, the consolidated fiber composite structure is removed from the device. At least one separate compensating element is arranged in the region of at least one height difference of the fiber composite structure, between the structure and one of the pressing elements, such that the at least one height difference with respect to the one of the pressing elements is compensated with the at least one compensating element.
