Beschreibung
Zusammenfassung:	Process for manufacturing a reinforced profile (1), comprising (a) manufacturing at least one daughter tape containing a first thermoplastic polymer and long chopped fibres by dispersing the first thermoplastic polymer in powder form over the long chopped fibres positioned in an isotropic manner; applying an AC electric field and heating under pressure; (b) optionally manufacturing a mother tape (3) by superposing and welding at least two daughter tapes obtained in step (a); and (c) manufacturing a reinforced profile using a daughter tape obtained in step (a) or a mother tape (3) obtained in step (b) by extruding a molten second thermoplastic polymer on at least one face of the daughter tape or on at least one face of the mother tape (3). Reinforced profile (1) obtained and use thereof.
