Description

Eisen-Nickel-Kobalt-Legierung Iron-nickel-cobalt alloy
Die Erfindung betrifft die Verwendung einer Eisen-Nickei-Kobalt-Legierung.The invention relates to the use of an iron-nickel-cobalt alloy.
In zunehmendem Maße werden Bauteile auch für sicherheitsrelevante Produkte, wie im Flugzeugbau, aus Kohlefaser verstärkten Kunststoffen (CFK) hergestellt. Für die Produktion derartiger Bauteile werden Werkzeuge (Formen) benötigt, in denen das viskose Harz-Kohlefaser-Gelege bei einer Temperatur von ca. 180°C ausgehärtet wird. Beim sog. RTM (Resin Transfer Molding) - Verfahren werden Kohlefasertextilien in die Form eingelegt, die Form evakuiert und anschließend das Harz in die Form injiziert. Nach dem Aushärten bei ca. 1800C wird das Bauteil aus dem Werkzeug entnommen. Als Werkstoffe kommen für diese Formen entweder C-Stähle oder eine Legierung mit geringem Ausdehnungskoeffizient (Eisen mit 36% Nickel, Ni36) zum Einsatz, die typischerweise einen mittleren Wärmeausdehnungskoeffizienten zwischen 1 ,6 und 2,5 x 10"6 K"1 hat.Increasingly, components for safety-related products, such as in aircraft, made of carbon fiber reinforced plastics (CFRP) produced. For the production of such components tools (forms) are required in which the viscous resin carbon fiber scrim is cured at a temperature of about 180 ° C. In the so-called RTM (Resin Transfer Molding) process, carbon fiber textiles are placed in the mold, the mold is evacuated and then the resin is injected into the mold. After curing at about 180 0 C, the component is removed from the tool. The materials used for these forms is either C-steels or an alloy having a low expansion coefficient (iron with 36% nickel, Ni36) is used, which typically has an average thermal expansion coefficient between 1, 6 and 2.5 x 10 "6 K '1.
Der Einsatz dieser RTM-Formen ist mit Schwierigkeiten und einem erheblichen Aufwand verbunden, da sich nach dem Aushärten das Bauteil schwer aus der Form wieder zu lösen ist und zusätzlich das Bauteil aufwändigen Nacharbeiten unterzogen werden muss, damit es den Ansprüchen an seine Funktion gerecht werden kann.The use of these RTM forms is associated with difficulties and a considerable effort, because after curing, the component is difficult to loosen from the mold and in addition the component must undergo extensive rework, so that it can meet the demands of its function ,
Der Erfindung liegt daher die Aufgabe zu Grunde, für diese Formen eine Legierung bereitzustellen, mit der genannte Schwierigkeiten einfach überwunden werden können.The invention is therefore based on the object to provide an alloy for these forms, with said difficulties can be overcome easily.

Ein bevorzugter Anwendungsfall für die Legierung wird im Flugzeugbau gesehen, wobei die Legierung als Formbauteil, insbesondere zur Erzeugung von CFK- Beschlägen mit der RTM-Technologie, eingesetzt werden kann. Andere Flugzeugbauteile, die ebenso in CFK-Leichtbauweise ausgeführt werden, können mit Bauteilen aus der vorgeschlagenen Legierung ebenfalls erzeugt werden.A preferred application for the alloy is seen in aircraft, wherein the alloy can be used as a molded component, in particular for the production of CFRP fittings with the RTM technology. Other aircraft components, which are also made of lightweight CFRP, can also be produced with components of the proposed alloy.
Gegenüber bisher zum Einsatz gelangenden Legierungen auf Basis von Ni 36 können Bauteile aus Formen dieser Legierung leicht entnommen werden, da die thermische Schrumpfung der Form nach dem Aushärtungsvorgang geringer ist. Durch eine geeignete Konstruktion der Form kann das Bauteil so entnommen werden, dass es seiner Funktion ohne Nacharbeiten gerecht wird.Compared to previously used alloys based on Ni 36, components made from shapes of this alloy can be easily removed, since the thermal shrinkage of the mold after the curing process is lower. By a suitable design of the mold, the component can be removed so that it will fulfill its function without reworking.
Durch die einfachere Entnahme des Bauteils aus der Form wird außerdem die Lebensdauer der Form erhöht, da keine scharfkantigen Werkzeuge zum Einsatz kommen müssen, um das Bauteil aus der Form zu lösenThe easier removal of the component from the mold also increases the life of the mold, since no sharp-edged tools must be used to release the component from the mold
