Description

ALUMINIUM-LEGIERUNGEN ZUR HERSTELLUNG VON FASER-VERBUNDWERKSTOFFEN ALUMINUM ALLOYS FOR THE PRODUCTION OF FIBER COMPOSITES

Beschreibungdescription

Die Erfindung betrifft Aluminium-Legierungen zur Herstel¬ lung von Faser-Verbundwerkstoffen.The invention relates to aluminum alloys for the production of fiber composite materials.

Es sind Faser-Verbundwerkstoffe bekannt, bei denen Bündel von Mineralfasern in eine metallische Matrix eingelagert sind. Als Mineralfasern werden z.B. Langfasern auf Al203- oder auf SiC-Basis verwendet. Als Matrixwerkstoffe werden neben zahlreichen anderen Metallen auch reines Aluminium oder konventionelle Aluminium-Legierungen wie z. B. AI Si7Mg, AlSi7MgO,6; oder AlCu4TiMg oder AlMglSiCu einge¬ setzt. Die Herstellung dieser Verbundwerkstoffe kann auf unterschiedliche Weise erfolgen, z.B. durch Druckinfil¬ trieren des schmelzflüssigen Matrixmaterials in eine aus Faserbündeln aufgebaute Vorform oder auf pulvermetallurgi¬ schem Wege.Fiber composite materials are known in which bundles of mineral fibers are embedded in a metallic matrix. Long fibers based on Al 2 0 3 or based on SiC are used as mineral fibers. In addition to numerous other metals, pure aluminum or conventional aluminum alloys such as e.g. B. AI Si7Mg, AlSi7MgO, 6; or AlCu4TiMg or AlMglSiCu used. These composite materials can be produced in different ways, for example by pressure infiltrating the molten matrix material into a preform constructed from fiber bundles or by powder metallurgy.

Faser-Verbundwerkstoffe mit einer auε reinem Aluminium bestehenden Matrix können hervorragende Festigkeits- und Steifigkeits-Eigenschaften aufweisen und sind für Anwen¬ dungen z.B. in Luftfahrt- oder Automobilbauteilen geeig¬ net . Aufgrund der geringen Festigkeit der unverstärkten Aluminium-Matrix sind diese Materialkombinationen jedoch nur sehr bedingt dazu geeignet, Bauteile mit nur partiel¬ ler Faserverstärkung herzustellen. Wegen der hohen Kosten der Mineralfasern ist jedoch eine nur partielle Verstär¬ kung von hoher wirtschaftlicher Bedeutung.Fiber composite materials with a matrix consisting of pure aluminum can have excellent strength and stiffness properties and are suitable for applications e.g. in aviation or automotive components. Due to the low strength of the unreinforced aluminum matrix, these material combinations are only suitable to a very limited extent for producing components with only partial fiber reinforcement. Because of the high cost of mineral fibers, however, only partial reinforcement is of great economic importance.

ÜRSÄΓZBLATT (REGEL 26) erreichen nicht die hervorragenden Festigkeits- Eigenschaften, wie Sie von den Faser-Verbundwerkstoffen mit einer reinen Aluminium-Matrix bekannt sind. Diese Ma¬ terialkombinationen sind daher ebenfalls nur sehr bedingt für Anwendungen geeignet.OVERHEAD SHEET (RULE 26) do not achieve the excellent strength properties that are known from fiber composite materials with a pure aluminum matrix. These combinations of materials are therefore also only suitable for applications to a very limited extent.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, Aluminium-Legierungen anzugeben, die aufgrund ihrer Eigen¬ schaften für die Herstellung von kostengünstigeren par¬ tiell faserverstärkten Bauteilen geeignet sind. Als Krite¬ rien für die Eignung müssen die Aluminium-Legierungen in Kombination mit Mineralfasern als Faser-Verbundwerkstoff hervorragende Festigkeits- und Steifigkeits-Eigenschaften aufweisen und gleichzeitig im unverstärkten Zustand eine gute Festigkeit besitzen.The object of the present invention is now to provide aluminum alloys which, owing to their properties, are suitable for the production of less expensive partially fiber-reinforced components.
