Definitions

  • the present invention relates to a method for producing an adhesive bond between a lightweight composite component and another component according to the preamble of claim 1 and an apparatus according to the preamble of the independent device claim.
  • the object of the present invention is to provide a method and a device which do not have the above-described disadvantages, in particular in which a stronger and stronger adhesive bond is achieved.
  • a lightweight composite component in particular a sandwich component as it is known from US 2002/0020033 A1 is known, comprising a core layer and two outer layers bonded to another component by an adhesive.
  • the components to be bonded are positioned prior to bonding to each other so that a gap is formed between them, wherein the gap preferably includes portions which are associated with the cover layers, and at least one portion which is associated with the core layer.
  • the components need not necessarily be uniformly spaced to form the gap, but for example, to compensate for tolerances in a range also be closer to each other. For a simple visual check, care should be taken to ensure that a minimum gap thickness of about 1 mm remains.
  • the gap is then sealed at the edge by sealing means which differ from the adhesive in at least one material parameter, in particular the viscosity, the sealing means including a filling volume together with one joining surface of the respective components.
  • this filling volume is filled up with an adhesive, wherein the adhesive has to be flowable in order to be suitable for filling, preferably a viscosity in the range of 1-30,000 mPas, more preferably in a range between 1 - 10000 mPas, more preferably in a range between 1-5000 mPas, particularly preferably in a range of 1-3000 mPas.
  • the viscosity must be present in the corresponding outside temperature range at which the components are bonded, in particular at a temperature in the range from 0 ° C to 45 ° C, preferably in the range from 15 ° C to 30 ° C, particularly preferably at a temperature of 20 ° C.
  • the process according to the invention has a multiplicity of advantages over the processes known from the prior art.
  • the sealing means according to the invention in the first place to use adhesive bonding by filling, which brings a better surface bonding by the adhesive, which has a lower viscosity than the sealant, by its fluidity a large-area wetting in direct contact between the components and the adhesive. This also counteracts trapped air, which have proven to be a common fault of highly loaded adhesive joints.
  • the adhesive passes through the padding even without this contact force over a large area in contact with the joining surfaces.
  • a method according to the invention has the advantage that the components can be positioned or aligned "dry", that is to say without applied adhesives, whereby misalignments can be corrected even more easily and / or have less pronounced effects, whereas in "wet" positioning, which is very difficult and with great effort to accomplish, displaced by misalignments, for example, the majority of the adhesive displaced from the splice and / or can be distributed unevenly.
  • the sealing means can be designed for effective protection against stresses such as UV radiation and / or corrosion, so that the internal adhesive can be less resistant to these stresses, in particular in favor of a stronger adhesive effect. Also, a rapid curing of the adhesive is not absolutely necessary, since they are held by the sealing means stationary in the filling volume.
  • the sealing means preferably have a peripheral thickness (ie distance of a filling volume limiting surface of the sealing means to an outer surface of the sealing means) between 0.5 and 5 cm, more preferably between about 1 and 2 cm on.

  • the adhesive bond between the individual components are heavily loaded and require a secure and durable adhesive bond, which can be ensured by a method according to the invention.
  • the cover layers are each arranged on two opposite sides of the core material, more preferably, the cover layers envelop the core material as a continuous layer on the entire surface.
  • At least one of the cover layers is preferably formed in the sandwich construction for receiving the bending moments and the expansion forces in the plate plane.
  • the core material is designed in particular to absorb forces transversely to the cover layer, so it preferably absorbs the thrust forces or the local pressure forces.
  • the adhesive bond of the present invention now bonds the cover layers together so that the bending and stretching stress is preferably transferred fully from the cover layer of one plate to the cover layer of the adjacent plate. At the same time, the adhesive bond preferably also transfers the transverse forces in the core completely from one plate to the other plate.
  • balsa wood As a core material in the sandwich of a lightweight core material is advantageously used, but which has sufficient compressive and shear strength to to absorb the mentioned loads of pedestrian and road bridges. Preference is given to using wood, with a density of less than 600 kg / m3, or a polymer foam, which is reinforced if necessary with fiber composite webs. Particularly preferred balsa wood, with a density less than or equal to 300 kg / m 3 , in particular between 200 and 300 kg / m 3 .
