摘要
A method is described whereby multilayer tailored fiber placement (TFP) preforms of any desired thickness may be easily produced without fixing threads or intermediate layers interfering. To this end, the invention provides that reinforcing fibers (1) are sewn onto a substrate (2) using a chemically or thermally meltable fixing thread (3) thus resulting in the formation of a reinforcing fiber structure (5a). The fixing thread (3) firstly serves to fix the reinforcing fibers (1) on the substrate (2) and is subsequently melted so that the fixing thread (3) disintegrates while pre-fixing the reinforcing fibers (1) and does not influence the mechanical properties of the reinforcing fiber structure (5a).
