Core layer for a sandwich composite component, sandwich composite component and method for producing a sandwich composite component

摘要

Core element (1) for a core layer (3) of a sandwich composite component (10), is claimed, where the core element shaped surface is arranged with a first main surface (11), a second main surface (12) and side surfaces (13). At least one undercut recess open toward first and/or second major surfaces. Independent claims are also included for: (1) a core layer for a sandwich composite component, where several core elements are arranged in planar manner; and (2) a sandwich composite component comprising a core layer and a cover layer provided with at least one of the major surfaces.
