Abstract
(DE)
Die Erfindung betrifft ein Herstellungsverfahren für ein Bauteil eines Rotorblattes, indem eine Herstellungsform (2) mit gekrümmter Auflagefläche (1) zur Verfügung gestellt wird, wenigstens ein biegsames Pultrudat (4) auf die Auflagefläche (1) gelegt wird, das wenigstens eine biegsame Pultrudat (4) mit einer Vakuumfolie (6) überdeckt wird, ein Vakuum erzeugt wird und das wenigstens eine biegsame Pultrudat (4) durch das Vakuum an die gekrümmte Auflagefläche (1) der Herstellungsform (2) vollflächig angedrückt wird.
(EN)
The invention relates to a method for producing a component of a rotor blade in that a production mold (2) with a curved support surface (1) is provided, at least one flexible pultruded product (4) is laid on the support surface (1), the at least one flexible pultruded product (4) is covered with a vacuum film (6), a vacuum is generated, and the at least one flexible pultruded product (4) is completely pressed against the curved support surface (1) of the production mold (2) by the vacuum.
(FR)
L'invention concerne un procédé de fabrication pour un composant d'une pale de rotor, selon lequel un moule de fabrication (2) comportant une surface d'appui (1) incurvée est prévu ; au moins un élément pultrudé (4) souple est appliqué à la surface d'appui (1), l'au moins un élément pultrudé (4) souple est recouvert d'une feuille sous vide (6) ; un vide est généré ; et l'au moins un élément pultrudé (4) souple est pressé sur toute la surface, à l'aide du vide, sur la surface d'appui (1) incurvée du moule de fabrication (2).
