Title (DE) VERFAHREN, SYSTEM UND FORMWERKZEUG ZUM HERSTELLEN VON BAUTEILEN AUS FASERVERBUNDWERKSTOFFEN
(EN) METHOD, SYSTEM AND MOULDING TOOL FOR PRODUCING COMPONENTS MADE OF FIBER COMPOSITE MATERIALS
(FR) PROCÉDÉ, SYSTÈME ET MOULE DE FORMAGE POUR LA FABRICATION DE PIÈCES EN MATÉRIAUX COMPOSITES RENFORCÉS PAR DES FIBRES
Abstract:
(DE) Bei einem Verfahren zum Herstellen von Bauteilen aus Faserverbundwerkstoffen wird mindestens ein Platzhalter in einer Aussparung (26) in einem Formwerkzeug (24) eingebracht, danach wird das Rohbauteil erstellt (4), der Platzhalter entfernt (6), mindestens ein Hebekissen in die Aussparung (26) eingebracht (8) und das Rohbauteil durch Aufblasen (10) des Hebekissens (20) aus dem Formwerkzeug (24) entnommen. In einem System zum Herstellen von Bauteilen aus Faserverbundwerkstoffen wird der Entformprozess durch eine Recheneinheit überwacht und gesteuert, um vorgegebene maximale Bauteilbelastungen nicht zu überschreiten. Durch den sanften Entformvorgang können Folgekosten bei der Reparatur oder Nachbesserung der Bauteile vermieden werden.
(EN) The invention relates to a method for producing components made of fiber composite materials, wherein at least one placeholder is introduced in a recess (26) in a moulding tool (24), the unfinished component is then created (4), the placeholder is removed (6), at least one lifting cushion is introduced (8) in the recess (26), and the unfinished component removed from the moulding tool (24) by inflating (10) the lifting cushion (20). In a system for producing components made of fiber composite materials, the demoulding process is monitored and controlled by a processor so as not to exceed specified maximum component loads. Consequential costs due to the repair or rework of the components can be prevented by the gentle demoulding process.
(FR) L'invention concerne un procédé de fabrication de pièces en matériaux composites renforcés par des fibres. Au moins un garde-place est inséré dans un logement (26) d'un moule de formage (24). Ensuite, la pièce brute est produite (4), le garde-place est éliminé (6), au moins un coussin de levage est placé (8) dans le logement (26) et la pièce brute est retirée du moule de formage (24) par gonflage (10) du coussin de levage (20). Dans un système de production de pièces en matériaux composites renforcés par des fibres, le processus de démoulage est surveillé et commandé par une unité de calcul afin de ne pas dépasser des sollicitations maximales prédéterminées des pièces. Le processus de démoulage en douceur permet d'éviter les coûts secondaires de réparation ou de reprise des pièces.
