Title (DE) VERFAHREN ZUR HERSTELLUNG THERMOPLASTISCHER PREFORMS
(EN) METHOD FOR PRODUCING THERMOPLASTIC PREFORMS
(FR) PROCÉDÉ DE FABRICATION DE PRÉFORMES THERMOPLASTIQUES
Abstract:
(DE) Um ein Verfahren zur Herstellung thermoplastischer Preforms (100) aus einem Faserwerkstoff (10) und einem reaktiven thermoplastischen Matrixwerkstoff (11) derart weiter zu verbessern, dass daraus faserverstärkte thermoplastische Kunststoffbauteile (200) besonders wirtschaftlich und leichtbaugerecht zu fertigen sind, wird vorgeschlagen, dass der Faserwerkstoff mit einem reaktiven thermoplastischen Matrixwerkstoff vor dem Ablegen auf einem Preformwerkzeug (13) innerhalb einer Imprägniervorrichtung (12) getränkt wird.
(EN) In order to further improve a method for producing thermoplastic preforms (100) from a fibrous material (10) and a reactive thermoplastic matrix material (11) in such a manner that fibre-reinforced thermoplastic components (200) can be manufactured therefrom in a particularly economical manner and lightweight design, the fibrous material is impregnated with a reactive thermoplastic matrix material prior to deposition on a preform tool (13), within an impregnation device (12).
(FR) L’objet de la présente invention est de perfectionner un procédé de fabrication de préformes thermoplastiques (100) à partir d’une matière fibreuse (10) et d’un matériau matrice (11) thermoplastique réactif de manière telle que les pièces en matière thermoplastique renforcée par des fibres (200) qui en résultent sont particulièrement économiques à produire et conviennent aux constructions légères. Selon l’invention, la matière fibreuse est imprégnée à l’aide d’un matériau matrice (11) thermoplastique réactif dans un dispositif d’imprégnation (12) avant d’être disposée dans un outil de préformage (13).
