Multi-layer sandwich component, useful in motor vehicle, comprises two cover layers connected via set of connecting portions, where one of cover layers has indentations facing opposite to the other cover layer

摘要

The component (1) comprises two cover layers (11, 12) connected via a set of connecting portions (13) in a force-conducting manner, where one of the cover layers has indentations facing opposite to the other cover layer. The indentations have higher density along a predetermined load path of the component. A core part is placed between the cover layers, where thickness of the core part is a distance between the cover layers. A bead filler layer is formed between the core part and one of the cover layers. The component (1) comprises two cover layers (11, 12) connected via a set of connecting portions (13) in a force-conducting manner, where one of the cover layers has indentations facing opposite to the other cover layer. The indentations have higher density along a predetermined load path of the component. A core part is placed between the cover layers, where thickness of the core part is a distance between the cover layers. A bead filler layer (3) is formed between the core part and one of the cover layers. The indentations of one cover layer extend up to the other cover layer, and/or to the bead filler layer, and/or to the core part. The connecting portions are materially connected in one of the cover layers, the core part and/or the bead filler layer. The core part is an elongate reinforcing strip (2) having greater elastic yield strength than the cover layers. The strip extends in an indentation-free region of the component along the predetermined load path and/or along another predetermined load path. The core part is a full-face core which is arranged over the entire surface between the cover layers. An independent claim is included for a method for manufacturing a sandwich component.
