Definitions
- the invention relates to the use of an iron-nickel-cobalt alloy.
- CFRP carbon fiber reinforced plastics
- tools 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.
- RTM Resin Transfer Molding
- 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.
- the invention is therefore based on the object to provide an alloy for these forms, with said difficulties can be overcome easily.
- the Ni content can be set in ranges of 32 to 34.5, if necessary also 32.5 to 33.5%.
- a preferred alloy is characterized by the following composition (in
- Another advantageous alloy to use is characterized by the following chemical composition (in mass%):
- the molds are machined as a milled part from thermoformed (forged or rolled) or cast solid material and then annealed.
- the alloy can also be used in the form of wire material, in particular as a welding additive in the production of the mold.
- 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.
- components made from shapes of this alloy can be easily removed, since the thermal shrinkage of the mold after the curing process is lower.
- the component can be removed so that it will fulfill its function without reworking.
- Table 1 lists exemplary chemical compositions for iron-nickel-cobalt alloys according to the invention (E1, E2, E3, E4, E5, E6) in comparison to other investigated iron-nickel-cobalt alloys (T1, U1). Element (%) i E1 E2 E3 E4 E5 E6
- the alloys according to the invention E1-E3 and E6 reach thermal expansion coefficient in the range of 1, 5- ⁇ 2.0x10 "-6 / K in the temperature range of 20-200 ° C.
- the alloys E4 and E5 according to the invention achieve an even lower expansion coefficient of about 1.3 ⁇ 10 -6 / K in the temperature range from 20 to 200 ° C., so that a combination of increased strength and simultaneously low thermal expansion was achieved with the alloys E4 and E5 ,
