Abstract:
1. A method for producing single- or multi-layered fiber performs by the TFP process, comprising: a) applying a release layer in the form of a PTFE film with a small layer thickness to a backing layer, b) laying fiber strands which are aligned substantially such that they are oriented with the flux of force onto the release layer, c) attaching the fiber strands by fixing threads to the backing layer to form a fiber preform with a desired material thickness, wherein the fixing threads form loops extending through the release layer and the backing layer, d) after completion of the TFP process, introducing the fiber preform into a fixing device, e) partially melting the fixing threads in the fixing device by heat being supplied, f) cooling the partially melted fixing threads to bind within the fiber preform, and g) detaching the backing layer, separated from the fiber preform by the release layer, from the fiber preform.
