摘要

Layer composition (1) has a first surrounding layer (5) and a second surrounding layer (3) and a central layer (7) is lying in between the first and the second surrounding layer. The central layer comprises oblong shaped gutter element (9). The gutter element has an arch-shaped at cross section in the transverse direction. The arc end point of base point (11) is designed on the first surrounding layer. Corresponding base lines (13) are designed in the longitudinal direction. The gutter element adjoins together on the base lines of the neighboring gutter element. The comb section (15) of the arches rests against the second surrounding layer. Independent claims are also included for the following: (1) Partial modules; and (2) Component.
