Title (DE) VERFAHREN ZUR HERSTELLUNG EINER INSTRUMENTENTAFEL FÜR EIN KRAFTFAHRZEUG
(EN) METHOD FOR PRODUCING A DASHBOARD FOR A MOTOR VEHICLE
(FR) PROCÉDÉ DE FABRICATION D'UN TABLEAU DE BORD POUR UN VÉHICULE AUTOMOBILE
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung einer Instrumententafel (1) für ein Kraftfahrzeug mit zumindest einem Funktionselement (5, 7), wobei die Instrumententafel (1) einen Instrumententafel-Träger (3) aufweist, in welchem Verfahren ein Faserhalbzeug (40) aus Naturfasern (41) und Thermoplastfasern (43) in einem Heizschritt bis über die Schmelztemperatur der Thermoplastfasern (43) erwärmt wird, und zwar unter Bildung einer aufgeschmolzenen Kunststoffmatrix (45), in der die Naturfasern (41) eingebettet sind, und anschließend in einem Form pressschritt das Faserhalbzeug (40) mit der aufgeschmolzenen Kunststoffmatrix (45) zu dem Instrumententafel-Träger (3) umgeformt wird. Erfindungsgemäß wird zur Bildung des Instrumententafel-Trägers (3) das Funktionselement (5, 7) in einem Kunststoff-Spritzgießschritt unmittelbar an einem, im Formpressschritt hergestellten Instrumententafel-Grundkörper (4) angespritzt. Der Instrumententafel-Grundkörper (4) wird mit zumindest einer Grundkörper-Ausnehmung (13) versehen, an deren Öffnungsrandbereich ein Anspritzprofil (15) ausgebildet ist, an dem das Funktionselement (5, 7) angespritzt wird.
(EN) The invention relates to a method for producing a dashboard (1) for a motor vehicle comprising at least one functional element (5, 7), wherein the dashboard (1) has a dashboard support (3), in which method a prepreg (40) of natural fibres (41) and thermoplastic fibres (43) is heated in a heating step to above the melting temperature of the thermoplastic fibres (43), specifically to form a melted polymer matrix (45), in which the natural fibres (41) are embedded, and subsequently the prepreg (40) with the molten polymer matrix (45) is shaped in a compression-moulding step into the dashboard support (3). According to the invention, to form the dashboard support (3), in a plastics injection-moulding step the functional element (5, 7) is moulded directly onto a main dashboard body (4) produced in the compression-moulding step. The main dashboard body (4) is provided with at least one main-body clearance (13), at the peripheral region around the opening of which there is formed a moulding profile (15), at which the functional element (5, 7) is moulded on.
(FR) L'invention concerne un procédé pour la fabrication d'un tableau de bord (1) pour un véhicule automobile, présentant au moins un élément fonctionnel (5, 7), le tableau de bord (1) présentant un support (3) de tableau de bord. Dans ce procédé, un produit semi-fini (40) en fibres naturelles (41) et en fibres thermoplastiques (43) est chauffé dans une étape de chauffage au-dessus de la température de fusion des fibres thermoplastiques (43), une matrice synthétique (45) fondue, qui enrobe les fibres naturelles (41), étant formée, et le produit semi-fini (40) en fibres, présentant la matrice synthétique (45) fondue, est ensuite moulé dans une étape de moulage par compression en support (3) de tableau de bord. Selon l'invention, pour la formation du support (3) de tableau de bord, l'élément fonctionnel (5, 7) est moulé dans une étape de moulage par injection d'un matériau synthétique directement sur un corps de base (4) de tableau de bord fabriqué dans l'étape de moulage par compression. Le corps de base (4) de tableau de bord est pourvu d'au moins un évidement (13) de corps de base présentant, au niveau de la zone de bord de l'ouverture, un profil de moulage par injection (15) sur lequel l'élément fonctionnel (5, 7) est moulé par injection.
