Abstract
(DE)
Die Erfindung betrifft eine Vorrichtung zum Herstellen von Vorformlingen (3) für Flugzeugstrukturbauteile (2), wobei die Vorrichtung eine Bereitstellungseinheit (6) aufweist, die eingerichtet ist, einen Schichtaufbau (13) mit mindestens einer Materiallage (4) eines thermisch aktivierbaren, flexiblen Faserverbundwerkstoffs zusammen mit einer an mindestens einer Außenseite des Schichtaufbaus (13) jeweils angeordneten Schutzfolie (14) bereitzustellen, wobei die Vorrichtung mindestens eine der Bereitstellungseinheit (6) in einer Förderrichtung (F) nachgelagerte Umformeinheit (7a, 7b) aufweist, die eingerichtet ist, den bereitgestellten Schichtaufbau (13) umzuformen. Es wird vorgeschlagen, dass der Schichtaufbau (13) zusammen mit der jeweiligen Schutzfolie (14) der Umformeinheit (Ta) oder einer der Umformeinheiten (7a, 7b) mit einem Querschnittsprofil, mit dem sich die Schutzfolie (14) oder mindestens eine der Schutzfolien (14) entlang einer Geraden (G) erstreckt, zuführbar ist.
(EN)
The invention relates to a device for producing preforms (3) for aircraft structural parts (2), the device having a delivery unit (6) which is designed to deliver a layered structure (13) having at least one material ply (4) of a thermally activatable, flexible, fibre-reinforced composite material together with a protective foil (14) arranged on at least one outer side of the layered structure (13), the device having at least one shaping unit (7a, 7b) which is situated downstream of the delivery unit (6) in a conveying direction (F) and is designed to shape the delivered layered structure (13). According to the invention, the layered structure (13) together with the corresponding protective foil (14) can be supplied to the shaping unit (Ta) or to one of the shaping units (7a, 7b) with a cross-sectional profile with which the protective foil (14) or at least one of the protective foils (14) extends along a straight line (G).
(FR)
L'invention concerne un dispositif servant à la fabrication de préformes (3) pour des éléments structuraux aéronautiques (2), ledit dispositif comprenant une unité de fourniture (6) qui est conçue pour fournir une structure en couches (13) pourvue d'au moins une couche de matériau (4) constituée d'un matériau composite renforcé de fibres flexible et pouvant être activé par voie thermique, conjointement avec une feuille protectrice (14) disposée sur au moins une face externe de la structure en couches (13), ledit dispositif comportant au moins une unité de formage (7a, 7b) montée en aval de l'unité de fourniture (6) dans une direction de transport (F) et conçue pour façonner la structure en couches (13) fournie. Selon l'invention, la structure en couches (13) peut être amenée conjointement avec la feuille protectrice (14) respective à l'unité de formage (Ta) ou à l’une des unités de formage (7a, 7b) avec un profil de section transversale avec lequel la feuille protectrice (14) ou au moins l’une des feuilles protectrices (14) s'étend le long d'une droite (G).
