Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen eines Hohlprofils (10), insbesondere eines Cockpitquerträgers für einen Kraftwagen, bei welchem Endlosfasern (22, 32) um einen die Innenkontur des herzustellenden Hohlprofils abbildenden Kern (48) zu einer Faserhohlstruktur (46) geflochten werden, wobei nach dem Flechten die Faserhohlstruktur (46) im elastischen Zustand zerstörungsfrei vom Kern (48) entnommen, durch Innendruckbeaufschlagung in eine Endkontur geformt und mit einem Kunststoff umspritzt wird.
