Correspondingly, the honeycomb must be machined in a complex mechanical removal manner, because otherwise there is the risk that the honeycomb parts compressed in the process in the edge region will be destroyed due to too little penetration of the plastic, in particular by the action of moisture. may swell

Embodiment Construction

[0023] Sandwich member 1 of the vehicle (see image 3 ), for example a part of a roof module or a cover of an openable roof such as a sliding roof or a sliding lift roof etc. has a layer structure with a central honeycomb structure 2 as a core layer and applied to a sandwich component Covering layer 5 or 6 on both sides or on the outer side 3 and inner side 4 of the sandwich component 1 .

[0024] The honeycomb structure 2 comprises a first honeycomb layer 7 and a second honeycomb layer 8 . exist figure 1 The first honeycomb layer 7 shown as the lower part and forms the inner lower honeycomb layer 7 in the sandwich member 1 than in figure 1 The second honeycomb layer 8 , which is shown as the upper part and forms the outer upper honeycomb layer 8 in the sandwich component 1 , has a larger surface area. The first lower honeycomb layer 7 has a particularly uniform thickness which is smaller than the thickness of the second upper honeycomb layer 8 . The first lower honeycomb ...

Abstract

The invention relates to a vehicle sandwich component (1) with a layer structure having a honeycomb structure (2), characterized in that the honeycomb structure (2) has a first lower honeycomb layer (7) ) and a second upper honeycomb layer (8), the first lower honeycomb layer (7) has at least one edge section (9) and a central honeycomb layer area or compression area (16), the edge section along the transverse direction Projecting laterally beyond the second upper honeycomb layer (8), the central honeycomb layer region or compressed region has a thickness reduced by compression relative to the edge section (9) and in this central honeycomb layer region or compressed Said second upper honeycomb layer (8) is arranged on the region, and the invention relates to a method for producing such a vehicle sandwich structure (1).

Description

technical field [0001] The invention relates to a vehicle sandwich component having a layer structure having a honeycomb structure; and to a method for producing a vehicle sandwich component. Background technique [0002] Such vehicle sandwich components are, for example, roof opening systems such as the cover of a sliding or wraparound roof, surface components of a roof module, lining components of a vehicle or a rear seat wrap shelf or a sliding sunroof. [0003] Sandwich components in vehicle construction are mostly implemented as surface components with a uniform component thickness. This applies in particular to components such as rear seat parcel shelves, sliding sunroofs or entire vehicle roofs. The core structure of these components is produced by means of a homogeneous honeycomb core with a constant honeycomb thickness. Honeycombs with a constant thickness cannot be used for components with increased strength requirements or with defined contours due to design, su...
