Definitions

  • the invention relates to the use of an iron-nickel-cobalt alloy.
  • CFC carbon fiber-reinforced composites
  • implements for producing such components, implements (molds) are needed in which the viscous resin-carbon fiber layer is cured at a temperature of approx. 180° C.
  • RTM resin transfer molding
  • carbon fiber textiles are added to the mold, the mold is evacuated, and then the resin is injected into the mold. After curing at approx. 180° C., the component is removed from the implement.
  • Materials used for these molds are either C steels or an alloy with a low coefficient of expansion (iron with 36% nickel, Ni36) that typically has a mean thermal expansion coefficient between 1.6 and 2.5 ⁇ 10 ⁇ 6 K ⁇ 1 .
  • RTM molds are associated with difficulties and significant complexity because after it is cured the component is difficult to release from the mold and in addition the component must undergo complex subsequent processing so that it can satisfy its functional demands.
  • the underlying object of the invention is therefore to provide an alloy for these molds, with which alloy the aforesaid difficulties can be overcome simply.
  • the alloy having a mean thermal expansion coefficient of ⁇ 2.0 ⁇ 10 ⁇ 6 /K in the temperature range from 20 to 200° C.
  • the Ni content can be adjusted ranging from 32 to 34.5%, where needed even 32.5 to 33.5%.
  • One preferred alloy is distinguished by the following composition (in % by weight):
  • Another alloy that can be used advantageously is distinguished by the following chemical composition (in % by weight):
  • the molds are made as milled parts from heat-formed (forged or rolled) or cast mass material and then annealed.
  • the alloy can also be used in the form of wire material, in particular as an added welding substance when producing the mold.
  • alloy is found in aircraft manufacture, wherein it is possible to use the alloy as a molded component, in particular for producing CFC fittings using the RTM technology.
  • Other aircraft components that are also embodied using the light-weight CFC construction can also be produced with components made of the suggested alloy.
  • components can easily be removed from molds of this alloy, because the thermal shrinkage of the mold is lower after the curing process. Given a suitable design for the mold, the component can be removed such that it can perform its function without subsequent processing.
  • Table 1 provides examples of chemical compositions for inventive iron-nickel-cobalt alloys (E1, E2, E3, E4, E5, E6) compared to other iron-nickel-cobalt alloys (T1, U1) that were investigated.
  • Inventive alloys E1-E3 and E6 attain thermal expansion coefficients ranging from 1.5- ⁇ 2.0 ⁇ 10 ⁇ 6 /K in the 20-200° C. temperature range.
  • the inventive alloys E4 and E5 attain an even lower expansion coefficient of about 1.3 ⁇ 10 ⁇ 6 /K in the 20 to 200° C. temperature range so that with the alloys E4 and E5 a combination of increased strength with simultaneously lower thermal expansion is attained.
