Title (EN) METHOD FOR PRODUCING MOULDED BODIES CONSISTING OF FIBRE-REINFORCED COMPOSITE MATERIALS
(FR) PROCÉDÉ DE FABRICATION DE CORPS MOULÉS COMPOSÉS DE MATÉRIAUX COMPOSITES RENFORCÉS PAR DES FIBRES
(DE) VERFAHREN ZUR HERSTELLUNG VON FORMKÖRPERN AUS FASERVERSTÄRKTEN VERBUNDWERKSTOFFEN
Abstract:
(EN) The invention relates to a method for producing moulded bodies consisting of fibre-reinforced composite materials, comprising the following steps: providing and degasifying a resin component, providing and degasifying a curing agent component, mixing the resin component and the curing agent component, and pouring the mixture of resin and curing agent components into a casting mould (20). To allow production of moulded bodies consisting of fibre-reinforced composite materials having improved mechanical properties and in particular to be able to produce bubble-free moulded bodies consisting of fibre-reinforced composite materials, it is proposed for the mixing to be carried out under a constant vacuum and pouring to be carried out with exclusion of air.
(FR) L'invention concerne un procédé de fabrication de corps moulés composés de matériaux composites renforcés par des fibres. Ledit procédé comprend les étapes suivantes consistant à : fournir et dégazer un produit résineux, fournir et dégazer un durcisseur, mélanger le produit résineux et le durcisseur et verser le mélange composé du produit résineux et du durcisseur dans un moule (20). L'invention vise à permettre la fabrication de corps moulés composés de matériaux composites renforcés par des fibres présentant des propriétés mécaniques améliorées et à pouvoir en particulier fabriquer des corps moulés sans soufflures composés de matériaux composites renforcés par des fibres. A cet effet, le mélange est effectué avec une dépression continue, et le remplissage est effectué à l'abri de l'air.
(DE) Dargestellt und beschrieben ist ein Verfahren zur Herstellung von Formkörpern aus faserverstärkten Verbundwerkstoffen, umfassend die folgenden Schritte: Bereitstellen und Entgasen einer Harzkomponente, Bereitstellen und Entgasen einer Härterkomponente, Vermischen von Harzkomponente und Härterkomponente, und Einfüllen der Mischung aus Harz- und Härterkomponente in eine Gießform (20). Um die Herstellung von Formkörpern aus faserverstärkten Verbundwerkstoffen mit verbesserten mechanischen Eigenschaften zu ermöglichen und insbesondere, um blasenfreie Formkörper aus faserverstärkten Verbundwerkstoffen herstellen zu können, wird vorgeschlagen, dass das Vermischen bei anhaltendem Unterdruck und das Einfüllen unter Luftabschluss durchgeführt werden.
