Definitions

  • the invention relates to a method for applying metallic layers to the surface of hollow, outwardly open components formed from fiber-reinforced plastics by galvanic means, in particular components with a spherically curved surface, the components being exposed to material-removing treatments during the coating process.
  • Metal foils or metal plates are applied to supports made of plastics, for example in the production of printed circuit boards, by means of adhesive with sufficient strength of the connection between support and support.
  • the films or plates can be applied in the manner mentioned without difficulty.
  • the carrier is a component with a spherically curved surface, metal foils or flat metal plates cannot be applied to the carrier without wrinkling.
  • a simpler route can be taken using electroplating technology to remove surfaces of non-metal components, e.g. made of plastics, completely or partially covered with metal layers.
  • Structural parts that have a load-bearing function for example parts of the load-bearing structure of aircraft such as missiles, airplanes or the like, must be designed with regard to the stress caused by the loads to be absorbed and with regard to the lowest possible structural weight.
  • Impairment of the strength of structural structural parts made of plastic treated in this way is particularly important if only a partial coating is provided.
  • the entire surface and, in the case of hollow components, the cavity surface as well are exposed to the caustic agent.
  • the object of the invention is to provide a method by means of which it is possible to galvanically provide the surface of structural structural parts formed on fiber-reinforced plastics with a firmly adhering metallic coating, for example a copper coating, without impairing the coating sections of the component surface against chemical and / or mechanical interference is prevented.
  • the object is achieved by the method features mentioned in the main claim and in an advantageous further embodiment of the invention according to the features of the subclaims.
  • a wrinkle-free, firmly adhering coating of the component surface is achieved by the method according to the invention. Furthermore, a secure covering of the sections of the surface of the component to be protected against chemical and / or mechanical influences is effected even on inner regions of the component surface that are difficult to access.
  • the cavity-induced buoyancy of the Component in the bath is neutralized during electrolysis and deformation of the component is also avoided by compensating for pressure differences, in particular with regard to the bath temperatures that occur during the coating process.
  • Figures 1 and 2 show the training in cross section in connection with parts of the electroplating system of known training.
  • the components to be coated shown are hollow wing sections which are formed from fiber-reinforced plastic and are open to the outside and are used as supporting structural parts on a missile.
  • the components are denoted overall by C in Figures 1 and 2 of the drawing.
  • the outer component surface is intended to be coated with copper in accordance with the aforementioned method for forming an antenna reflector.
  • section G of the component wall is shown, which extends beyond the cavity opening or beyond the finished component dimension is outstanding and serves to receive the end wall E or E 'for the liquid-tight closure of the cavity for the duration of the coating process and which is separated from the component C after the process step of the galvanic coating, in such a way that the component has its prescribed finished size receives.
  • A also denotes the container for the electroplating bath, into which the components C to be coated are immersed in a known manner. For the sake of simplicity, a complete representation and description of the electroplating system has been omitted.
  • the cavity of the components C is filled with an electrically neutral liquid D during the coating process and vented to the outside by means of a vent line F which is led out of the bath.
  • the cavity can also be closed off by an end cover E which can be fastened to the wall section G according to the construction according to FIG.
  • the wall section G has a receiving flange for the cover.
