- the predetermined breaking lines 14 are formed by weakenings in the form of notches in the stiffening surface 1 1 P injection-molded onto the surface element 10.
- the surface element 10 may also be provided with weakenings.
- the weakenings are designed and configured to cause material failure at a predetermined location when an applied force exceeds a predetermined maximum force (eg, in a so-called ADR train).
- the structural assembly 1 described with reference to FIGS. 1 to 19 is thus designed as an organic sheet plastic hybrid component and therefore satisfies high stability requirements with a particularly low weight. By integrating a plurality of stiffening elements and interface elements in the structural assembly 1, the production is also particularly simple. Because so the number of necessary connection operations can be significantly reduced.
- the surface element 10 is made of organic sheet and thus made of a thermoformable composite material.
- the organic sheet is provided in flat form and thus as a sheet material.
- a corresponding piece is cut or punched out of the surface of the organic sheet.
- a corresponding piece of organo sheet is already made in this form and no longer needs to be cut.
- the blank from which the surface element 10 is to be produced is reshaped. Since the organic sheet is a thermoformable material, this can be done in a simple manner by means of thermoforming, that is, by heating the blank with subsequent mechanical deformation.
- the stiffening elements 1 1A-1 1 P and the interface elements 12A-12Q are in the present case not made of organic sheet produced. Instead, they consist of a plastic and are molded by means of plastic injection molding to the surface element 10. The stiffening elements 1 1A-1 1 P and the interface elements 12A-12Q are connected in this way cohesively with the surface element 10. In order to simplify the production of the structural assembly 1 as possible, the forming of the surface element 10 can be carried out in the same tool as the injection molding.
- thermoplastic material of which the fiber material piece embedding matrix of the organic sheet it may be advantageous to use the same plastic material by injection molding to form the stiffening elements 1 1A-1 1 P and the interface elements 12A-12Q.
- the stiffening ribs 1 1 D and the outgoing support ribs 1 10 forming injection molding material is injected into the injection molding tool at various points.
- the injection molding material flows (depending on the arrangement of the injection points) of the support rib 1 10 forming portion of the injection mold in the stiffening rib 1 1 D forming portion or vice versa.
- the support ribs 1 10 are formed with open ends 1 1 1, no two fronts of injection material flows meet here.
- the fronts enter into a cohesive connection.
- stiffening rib 1 1A-1 1 D, 1 1 F-1 1 H, 1 1 N but possibly less strong loadable, as in areas which are formed by a single injection molding material flow (in particular, the compound in tearing a tensile load).
- the provided with support ribs 1 10 stiffening ribs 1 1 D therefore have a particularly high stability against a tensile load.
- An incomplete consolidation of a region (eg in the region of the end edge 106) of the surface element 10 may be effected by injection molding (or generally by heating). The surface element 10 is then not completely pressed in the area to obtain the incomplete consolidation.
