Definitions

  • the invention relates to a composite part composed of at least one primary component and permanently connected to it, at least one secondary component, which components are essentially permanently connected to one another.
  • Monolithic parts or parts that are made from one material usually have a specific property profile that cannot be changed significantly, with favorable, but also disadvantageous individual properties for a planned use.
  • constructive measures which often require a lot of effort, individual unfavorable part properties can be weakened or switched off, an advantageously coordinated overall property profile of a part with regard to the technical and economic requirements for this is generally not feasible.
  • the invention is based on the object of creating a composite part which is simple to set up, allows a large number of individual property combinations to be created and can be produced inexpensively.
  • the primary component (s) consists of a light metal or a light metal alloy with a density of less than 4.5 kg / dm 3 and the secondary component (s) is formed from a non-metallic material or a mixture of non-metallic and metallic material (Are) and the mechanical property of the components to create the property of the composite part is coordinated.
  • the advantages achieved by the invention are, in particular, that parts can be produced with a property profile that is precisely tailored to their use.
  • the use of light metal or a light metal alloy is important according to the invention because, on the one hand, this material can be shaped cheaply into diverse geometric designs of the primary component and, on the other hand, compatibility with non-metallic materials enables a broad spectrum of a property profile of the composite part.
  • the good workability and workability, high corrosion resistance to acids, a wide range of coating options and a low part weight are advantages of using light metal.
  • a treatment of the metal partial surface or the application of an adhesion promoter can be provided, whereby a connection or a molding or forming and the like with non-metallic material can be achieved by injection molding, thermoforming, extrusion and other processes is.
  • the secondary component can now also have a supporting function, it may also be possible to particularly shape and / or reduce the cross section of the primary component.
  • the non-metallic material part of the secondary component contains fibers. This makes it possible to provide special or direction-dependent properties of the non-metal component.
  • the secondary components are formed at least partially from wood, a wood derivative or a material from annual plants. Not only can the area of application of composite parts be expanded, but also a high level of economy manufacturing or comparatively low part costs can be achieved.
  • Extremely light composite parts with a high thermal insulation effect can be produced if the secondary component is homogeneously foam-shaped.
  • An isotropy of the cavities in the non-metallic part is important on the one hand for a flat support of the metallic primary component for a reliable achievement of the desired mechanical properties and on the other hand for an evenly distributed specific weight of the part.
  • the non-metallic material part of the secondary component contains thermoplastic material, a favorable shaping with increased temperature and immediately after an at least partial cooling can be used in accordance with the load.
  • the metallic component and the non-metallic component separately and then to connect them, which can include advantages in terms of production technology, the components ultimately being joined by adhesive bonding.
  • the part is produced by extrusion, preferably at elevated temperature, it has the highest geometrical accuracy in the longitudinal direction and can advantageously be used or used for long composite parts with a special property profile immediately after cooling.
  • the metallic primary component encloses the cross-section of the secondary component formed at least partially from non-metallic material, on the one hand protection of the non-metallic part against UV radiation and oxidation or weathering is possible, on the other hand a particularly good mechanical use of the Light metal cross section can be achieved.
  • the metallic primary component (s) is flat and is (are) connected at least on one side to a secondary component.
  • a metallic primary component is tubular and is externally encased by a secondary component consisting essentially of a non-metallic material.
  • Individual parts can be connected to form long lines, for example by gluing, and form temperature-stable systems.

Abstract

L'invention concerne une pièce composite comprenant au moins un composant primaire et au moins un composant secondaire, lié indétachable au primaire, lesdits composants étant liés sensiblement indétachables entre eux. En vue de configurer la pièce pour une pluralité de sollicitations diverses à action uniforme, l'invention est caractérisée en ce que le(s) composant(s) primaire(s) est (sont) constitué(s) par un métal léger ou en un alliage en métal léger, d'une densité inférieure à 4, 5 kg/dm3, et en ce que le(s) composant(s) secondaire(s) est (sont) formé(s) par un matériau non métallique ou par un mélange de matériaux non métalliques et métalliques, et en ce que la propriété mécanique des composants est réglée de manière à avoir une propriété déterminée de la pièce composite.
