Abstract: The invention relates to a method for producing a self-reinforced thermoplastic composite material including: providing strips of a thermoplastic and weaving the plastic strips into a base fabric. The plastic strips for this are produced by at least the following steps: producing pre-stretched fibres from a partially crystalline polyester homopolymer with a melting point by extrusion on at least one spinning nozzle and subsequent stretching and joining a plurality of pre-stretched endless fibres lying next to and/or above one another to a matrix of an amorphous polyester homopolymer at a processing temperature T2<T1, wherein the temperature difference between T1 and T2 is at least ?T=30° C.
