A reinforcing structure made of a sheet-like cellular base material which comprises material attenuations (3) in a distribution over its area in a view from above, wherein the material attenuations sub-divide the base material into a multitude of material islands (1R; 1T) which are delineated from each other by the material attenuations (3) but are still connected to each other, wherein (a) the material islands (1R; 1T) are convex base polygons in a view from above; (b) a respective plurality of the material islands (1R; 1T) jointly form a convex and preferably regular compound polygon (1H) in a view from above; and (c) the compound polygons (1H) differ, in their number of corners and/or in a ratio of the lengths of their sides, from the base polygons which form the material islands (1R; 1T).
A reinforcing structure made of a sheet-like cellular base material which comprises material attenuations in a distribution over its area in a view from above, wherein the material attenuations sub-divide the base material into a multitude of material islands which are delineated from each other by the material attenuations but are still connected to each other, wherein
The reinforcing structure according to the preceding claim, wherein the strip-shaped depressions preferably each extend up to one of the material attenuations.
The reinforcing structure according to the preceding claim, wherein a cross-sectional area of the bridges is compressed and thereby reduced as compared to the material islands in the thickness direction of the reinforcing structure.
A reinforcing structure made of a sheet-like cellular base material which comprises material attenuations in a distribution over its area in a view from above, wherein the material attenuations sub-divide the base material into a multitude of material islands which are delineated from each other by the material attenuations but are still connected to each other, wherein
The composite according to the preceding claim, comprising another cover layer, wherein the reinforcing structure is arranged between the cover layers, and the bonding compound permeates the reinforcing structure and connects the cover layers in a material bond.
