  • these molded ribs lead to marks in the visible side of the outer lining part, so that the required surface quality can not be ensured.
  • CONFIRMATION COPY are produced and only then the reinforcing member is joined to the outer trim part.
  • a subsequent joining process takes place in which the reinforcing part is joined to the outer covering part.
  • the method according to the invention moreover, a weight saving on the body outer part in the range of about 50% compared to conventional body exterior parts can be achieved, in which the reinforcing member has been produced by conventional injection molding technology.
  • the invention not only allows backing / stiffening conventional injection or metal parts, but allows a significant reduction in the wall thickness of the outer trim part over conventional exterior trim parts.
  • the outer lining part can be weakened conscious and the lost stiffness thereby be brought in by the EPP stiffening part.
  • the provision of the reinforcing part made of the expanded polypropylene particle foam also achieves improved thermal insulation and an improvement in the acoustic properties of the self-supporting body outer part.
  • the method according to the invention extended constructive possibilities with regard to the design of the body outer part.
  • a geometric limitation of the body outer part due to no longer necessary injection molding or pressing process which particularly homogeneous and thin wall thicknesses can be achieved deleted.
  • a functional integration can be achieved by, for example, stiffening ribs are provided on the reinforcing member, which - unlike conventional methods - not appear on the surface of the body outer part, whereby a high surface quality of the body outer part can be achieved.
  • the body outer part with improved creep behavior and improved performance.
  • the reinforcing effect by the reinforcing member is not limited solely to an elastic bedding of the outer lining part, but the bending and torsional rigidity of the entire self-supporting body outer part is considerably increased by the reinforcing member.
  • the outer lining part is supported substantially over the entire area with the reinforcing member.
  • the outer cladding part is backfilled almost over the entire area with the reinforcing part formed from the expanded polypropylene particle foam.
  • the reinforcing member can also be joined only partially or locally with the outer trim part.
  • the transition region should not be reflected in the outer surface of the outer trim part, because this would result in a reduction of the surface quality.
  • a further advantageous embodiment of the invention provides that a film is attached to a surface of the reinforcement part, which lies outside the joining region between reinforcing part and outer lining part, welded locally, an injection molded part or the joining surface is compacted by a thermal process to a film-like skin.

  • the outer lining part can be produced for example as a molded part. If this injection-molded part has a very small wall thickness ( ⁇ 1 mm), it is advisable to connect the injection-molded part directly to the injection part (the mold half of the injection-molding tool which forms the Class A surface) after opening the molding tool with the reinforcement part in order to prevent damage to the part thin-walled injection molded part in the course of handling to avoid.

  • the self-supporting body outer part 10 comprises an outer lining part 12 and a reinforcing part 14.
  • the reinforcing part 14 is first produced from an expanded polypropylene particle foam.
  • the outer lining part 12 is also produced in a separate manufacturing step, wherein only then the reinforcing member 14 is joined to the outer lining part 12.

  • a thin-walled injection-molded part or thin-walled metal part is used as the outer lining part 12, then it is advisable to leave this component in the associated molding tool, while the joining process is carried out with the reinforcing part 14; In this way, a handling of the thin-walled outer trim part 12 is avoided and it is ensured that the mold, which images the desired outer contour of the outer trim part 12, this protects and supports during the joining process.
  • an essential aspect in the production of the outer lining part 12 is that a surface 20 of the outer lining part 12, which is a visible part, has a particularly good surface quality.

  • the wall thickness of the metallic outer lining part 12 is advantageously between a few tenths of a millimeter and a millimeter. With thin wall thicknesses of the outer trim part 12, a further (final) shaping of the outer trim part 12 may take place when the reinforcing part 14 is pressed on; At the same time, cooling of the outer covering part 12 and thus adhesion of the outer covering part 12 to the reinforcing part take place by pressing on the cool reinforcing part 14.

  • a film 26 is attached to a surface 28 facing away from this joining surface 22.
  • an injection molded part not shown here, can be welded on or the surface 28 can be compacted by a thermal process into a foil-like skin. In this way, the surface 28 is protected and / or the rigidity of the body outer part 10 is increased.
  • reinforcing fibers can already be arranged or introduced during the production of the reinforcing member 14.
  • one or more injection-molded parts for example with a correspondingly provided thread, can preferably be arranged on the surface 28, so that the reinforcement part 14 can be attached to corresponding body structures of a motor vehicle in a particularly simple manner.
