Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung eines Hybridbauteils, das aus mindestens zwei voneinander verschiedenen Werkstoffen hergestellt wird, wobei das Verfahren die folgenden Schritte umfasst: - Bereitstellen eines Substrates aus einem Substratwerkstoff, auf das wenigstens ein Funktionselement in einem Funktionsbereich des Substrates aufgebracht werden soll, - Erstellen einer ersten Funktionsschicht aus einem duroplastischen Harzsystem auf das Substrat zumindest innerhalb des Funktionsbereiches des Substrates, - Aufbringen wenigstens einer zweiten Funktionsschicht aus einem thermoplastischen Werkstoff auf die erste Funktionsschicht, - wobei das duroplastische Harzsystem und der thermoplastische Werkstoff so gewählt sind, dass beide nach dem Konsolidieren eine stoffschlüssige Verbindung eingehen, und - Aufbringen eines von dem Substratwerkstoff verschiedenen thermoplastischen Werkstoffes auf das Substrat im Bereich der zweiten Funktionsschicht, um das Funktionselement auf dem Substrat herzustellen.
Abstract:
The invention relates to a manipulating tool (40) for producing a plastic material part comprising at least a reinforcing element made of at least one fibrous insert made of a composite material, the manipulating tool comprising a shaping area (42) arranged to receive and hold the fibrous insert, the shaping area comprising a forming system (100) made of mobile independent elements (102), the forming system (100) being able to impart the shape of one side of the reinforcing element to the fibrous insert.
Abstract:
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.
Abstract:
A frame of a seat back includes a first polymeric material and a reinforcing composite layer that includes a second polymeric material and a plurality of fibers impregnated in the second polymeric material. A method of forming the frame includes supporting the reinforcing composite layer on moveable members in a mold. The moveable members are extended to an extended position in the mold. The first polymeric material is introduced in a molten state into contact with the reinforcing composite layer. The reinforcing composite layer is displaced away from the moveable members by introducing the first polymeric material in the molten state between the moveable members and the reinforcing composite layer while the moveable members are in the extended position. The first polymeric material is solidified in the mold and the moveable members are retracted from the first polymeric material to release the frame from the mold.
Abstract:
The present disclosure relates to an airbag cover (17), which comprises at least one door portion (19a, 19b) adapted to be opened to allow at least a portion of an airbag (9) to be deployed, at least one hinge portion (21 a, 21 b) located adjacent to a side of the door portion and being adapted to provide a hinge for the door portion when opening, and at least one reinforcement portion (23) at least partly surrounding the at least one door portion and the at least one hinge portion. The airbag cover comprises a mesh member (35), a first portion (39a, 39b) of the mesh member being located in the at least one reinforcement portion and a second portion (41 a, 41 b) of the mesh member being located in the at least one hinge portion. The at least one reinforcement portion comprises at least one rib (59) protruding in a first direction (D 1 ). The first portion of the mesh member has a non-planar cross-section by the mesh member being moulded into a portion of the at least one rib, such that the mesh member traverses the at least one rib. The disclosure further relates to a mesh member (35) for use in an airbag cover (17), a vehicle interior panel, e.g. a vehicle interior panel for a dashboard (1), and a method for making an airbag cover (17).
Abstract:
Procédé de fabrication d'une pièce de structure hybride (1) de véhicule automobile caractérisé en ce qu'il comprend les étapes au cours desquelles, on met en forme une nappe de matériau métallique pour former une pièce de métal (2), on solidarise une ou plusieurs bandes de renfort (3) formées de fibres continues enrobées avec une matrice polymère sur une nappe composite (4) formée de fibres imprégnées dans une matrice polymère thermoplastique, pour créer une nappe de renfort complexe (5), on dépose la pièce de métal (2) et la nappe de renfort complexe (5) dans un moule (10), en arrangeant la nappe de renfort complexe (5) de sorte que la nappe composite (4) est disposée pour venir en contact avec une des faces (23, 24) de la pièce de métal (2), et on ferme le moule pour conformer par estampage et faire adhérer le renfort complexe (5) sur ladite face de la pièce de métal (2).
Abstract:
A method of making a vehicle interior panel substrate (10) with a reduced thickness portion along a boundary (24, 24') of an airbag door (20, 20') includes molding the substrate using a substrate mold (100) that includes a movable mold member (106, 106'). The movable mold member (106, 106') is part of a mold section and moves with respect to other portions of the mold section during the molding process to form the reduced thickness portion, which may include a hinge (22 22') or a tear seam (16). The mold member moves after plastic material is introduced into the mold cavity (108). The plastic material is allowed to expand when substrate mold sections are moved away from each other. Plastic material expansion may be part of a structural gas injection (SGI) process. A scrim material (26) or other hinge reinforcement (26) may be molded into the substrate.
