Abstract
A method for producing single- or multi-layered fiber preforms by the TFP process with fiber strands, aligned substantially to be oriented with the flux of force, laid on a backing layer and attached by fixing threads, to form a fiber preform with a desired material thickness and without a backing layer. A release layer is applied at least in certain regions to the backing layer and, after completion of the TFP process, the fiber preform is introduced into a fixing device, in which at least some of the fixing threads are melted. Subsequently the backing layer, separated from the fiber preform by the release layer, is detached from the fiber preform. The fiber preforms have a virtually optimum fiber structure without flaws along with a desired material thickness and are predestined for the production of composite components for load-bearing components that must withstand high mechanical loads.
