Abstract

A deformable industrial fabric has warp ends and the picks consisting alternatingly of C fibres or metal wire. The number of warp ends and/or picks consisting of C fibres is greater than that made of metal wire.

Description

Die Erfindung betrifft ein verformbares, technisches Gewebe zur Herstellung von Bauteilen oder Strukturteilen.The invention relates to a deformable, technical fabric for the production of components or structural parts.

Aus der DE 31 44 653 A1 sind Fasergewebe bekannt, bei denen die Kettfäden und die Schußfäden mit elektrisch leitfähigem Material umhüllt sind. Das Fasergewebe bildet eine leitfähige Barriere zur Verteilung von Strömen und soll Flugzeuge vor Blitzschlag-Schäden schützen. Weiter sind Fasergewebe mit eingewebten Aluminium-Drahteinlagen zur Herstellung oder Verbesserung der elektrischen Leitfähigkeit bekannt. Die Drähte sind jedoch so dünn, daß sie dem Gewebe keine Eigensteifigkeit vermitteln. DE 31 44 653 A1 discloses fiber fabrics in which the warp threads and the weft threads are covered with electrically conductive material. The fiber fabric forms a conductive barrier for the distribution of currents and is intended to protect aircraft from lightning damage. Furthermore, fiber fabrics with woven-in aluminum wire inserts for producing or improving the electrical conductivity are known. However, the wires are so thin that they do not impart any inherent stiffness to the fabric.

Der Erfindung liegt die Aufgabe zugrunde, ein technisches Gewebe zu schaffen, das mechanisch verformbar ist und im verformten Zustand verharrt.The invention has for its object to provide a technical fabric that is mechanically deformable and remains in the deformed state.

Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Hauptanspruchs gelöst. Die Unteransprüche betreffen vorteilhafte Ausgestaltungen der Erfindung.This object is achieved by the subject matter of the main claim. The subclaims relate to advantageous refinements of the invention.

Durch den Gegenstand der Erfindung ergeben sich folgende Vorteile:

  • Herstellmöglichkeit von eigensteifen Formelementen aus Faserhalbzeug mit geringen Verformungskräften maschinell und/oder manuell.
  • Beschickung der formgebenden Bauvorrichtung (Laminiervorrichtung) mit vorgeformten Faserelementen in kürzester Zeit mittels Roboter und/oder manuell.
  • Keine oder nur einzelne Haltepunkte der vorgeformten Faserelemente in der Laminiervorrichtung erforderlich.
  • Keine Überspannung von Kanten und Ecken beim Drapieren.
  • Erhöhung der Bruchzähigkeit des Faserverbundwerkstoffes durch Metallarmierung.
  • Verbesserung des Schadensverhaltens der Bauteile aus diesem Werkstoff.
The following advantages result from the subject matter of the invention:
  • Possibility of producing inherently rigid molded elements from semi-finished fiber with low deformation forces by machine and / or manually.
  • Loading of the shaping construction device (laminating device) with preformed fiber elements in the shortest possible time by means of robots and / or manually.
  • No or only individual breakpoints of the preformed fiber elements in the laminating device are required.
  • No over-tensioning of edges and corners when draping.
  • Increasing the fracture toughness of the fiber composite material through metal reinforcement.
  • Improvement of the damage behavior of the components made from this material.
