  • FIG. 18 shows a cross-sectional view of a component 10 in a further embodiment, wherein a spacer strip 55 perpendicular to the cover layers 20 is provided.
  • the orientation of the fibers / profile of the spacer bar 55 may preferably be the same as the roof-shaped elements 50 in the direction B, wherein the direction B extends perpendicular to the plane of the page. However, this is not mandatory.
  • the cover layers 20 are each oriented in the direction A.
  • the component 10 is comparable to the construction of the component 10 shown in FIGS. 1 a - c, but supplemented by the spacer strip 55. It can be provided that a plurality of spacer strips 55 are arranged spaced apart from one another within the lightweight layer 30 and that one or more roof-shaped elements 50 are located between the spacer strips 55.
  • FIG. 19 A further embodiment of a component 10 is shown in FIG. 19, with spacer strips 55 being provided at the edge, which seal the lightweight layer 30.
  • the construction of the component 10 essentially corresponds to the construction of a component 10 shown in FIGS. 1 a - c and FIG. 18.
  • spacer strips 55 are not only provided on the edge side, but one or more spacer strips are arranged within the lightweight layer 30 next to the peripheral spacer strips 55, ie a combination of the embodiments of a component 10 shown in FIGS.
  • the edge spacers 55 may comprise the lightweight layer 30 and form a frame around the lightweight layer 30. It is conceivable first to form the lightweight layer 30, then to surround the lightweight layer 30 with a peripheral frame of peripheral spacer strips 55, and then to apply a cover layer 20 on one side or both sides of the lightweight layer 30 thus formed and provided with peripheral frames.
  • the frame of the edge-side spacer bars 55 does not necessarily have to be completely encircling and completely enclose the lightweight layer 30; it is equally possible to execute the frame only partially encircling or to provide one or more openings, for example by filling the intermediate spaces 40 in the lightweight layer 30 can be done.

Abstract

L'invention concerne un composant comprenant au moins une couche de recouvrement et au moins une couche de construction légère, la couche de construction légère et la couche de recouvrement s'appliquant l'une sur l'autre, au moins partiellement, indirectement et/ou directement. L'invention concerne en outre un procédé de production d'un tel composant.
