Abstract
In a method, multilayer tailored fiber placement (TFP) preforms of any desired thickness may be easily produced without fixing threads or intermediate layers interfering. Reinforcing fibers are sewn onto a substrate using a chemically or thermally meltable fixing thread thus resulting in the formation of a reinforcing fiber structure. The fixing thread firstly serves to fix the reinforcing fibers on the substrate and is subsequently melted so that the fixing thread disintegrates while pre-fixing the reinforcing fibers and may not influence the mechanical properties of the reinforcing fiber structure.
