Title (EN) MOULD CORE COMPRISING EXPANSION MATERIAL
(FR) NOYAU DE MOULE À MATÉRIAU EXPANSIBLE
(DE) FORMKERN MIT EXPANSIONSMATERIAL
Abstract:
(EN) The invention relates to a mould core for producing a fibre-reinforced component, particularly an undercut and/or hollow component, comprising a support core (2) that provides a basic shape for the mould core (1), and a coating in at least one surface region (4). According to the invention, the coating comprises an expansion material (3) that expands when the temperature rises such that, as the component is being produced, reinforcing fibres (13) can be pressed against an inner side (19) of a moulding tool (12).
(FR) L'invention concerne un noyau de moule pour la fabrication d’une pièce renforcée de fibres, en particulier d'une pièce en contredépouille et/ou creuse, comprenant un noyau support (2), qui spécifie une forme de base du noyau de moule (1), et un revêtement appliqué dans au moins une zone superficielle (4). Selon l’invention, le revêtement comprend un matériau expansible (3) qui, lorsque la température augmente, se dilate de telle sorte que, lors de la fabrication de la pièce, des fibres de renfort (13) peuvent être comprimées contre une face interne (19) d'un moule (12).
(DE) Die Erfindung betrifft einen Formkern zur Herstellung eines faserverstärkten Bauteils, insbesondere eines Hinterschnitt-und/oder Hohlbauteils, mit einem Stützkern (2), der eine Grundform des Formkerns (1) vorgibt, und mit einer in zumindest einem Oberflächenbereich (4) angeordneten Beschichtung. Erfindungsgemäß umfasst die Beschichtung ein Expansionsmaterial (3), das bei einer Temperaturerhöhung expandiert, so dass bei der Herstellung des Bauteils Verstärkungsfasern (13) an eine Innenseite (19) eines Formwerkzeugs (12) pressbar sind.
