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 ° C, the component is removed from the tool.
- the materials used for these molds are either C-steels or a low expansion coefficient alloy (36% nickel, Ni36 iron), which typically has a mean thermal expansion coefficient between 1.6 and 2.5 x 10 -6 K -1 .
- the invention is based on the object to provide for these forms an alloy with which said difficulties can be overcome easily.
- the Ni content can be set in ranges from 32.5 to 33.5%.
- Another advantageous alloy to use is characterized by the following chemical composition (in mass%): Ni 32.5 to 33.5% Co > 3.5 to ⁇ 4.5% Not a word Max. 0.05% Cr Max. 0.05% C Max. 0.009% Mn Max. 0.04% Si Max. 0.03% S Max. 0.003% N Max. 0.004% Ti Max. 0.01% Cu Max. 0.05% P Max. 0.005% al 0.001 to 0.05% mg Max. 0,0008% Ca Max. 0.003% Zr Max. 0.05% O Max. 0.005% Remainder Fe and production-related admixtures, wherein the alloy in the temperature range of 20 to 200 ° C has a mean thermal expansion coefficient ⁇ 1.3 x 10 -6 / K.
- 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 part, 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 (%) E1 E2 E3 E4 E5 E6 C 0,002 0.047 0,002 0,008 0,002 0,036 S 0.0023 0.0009 0.0006 0.0015 0.0004 0.0011 N 0.001 0.001 0.001 0.001 Cr 0.02 0.07 ⁇ 0.01 ⁇ 0.01 ⁇ 0.01 0.01 Ni 34,20 34.25 32.75 32,80 32,80 32,55 Mn ⁇ 0.01 ⁇ 0.01 ⁇ 0.01 ⁇ 0.01 ⁇ 0.01 ⁇ 0.01 Si 0.07 ⁇ 0.01 ⁇ 0.01 ⁇ 0.01 ⁇ 0.01 ⁇ 0.01 Not a word 0.01 0.02 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01 0.01
- inventive alloys E1-E3 and E6 achieve coefficients of thermal expansion in the range of 1.5- ⁇ 2.0x10 -6 / K in the temperature range of 20-200 ° C.
- inventive alloys E4 and E5 achieve an even lower expansion coefficient of about 1.3 ⁇ 10 -6 / K in the temperature range of 20 and 200 ° C, so that with the alloys E4 and E5, a combination of increased strength was achieved with low thermal expansion ,
