Abstract

A honeycomb core construction that includes at least two honeycomb cores and a connection layer that is disposed between the honeycomb cores. The connection layer is configured so as to be gas-permeable, and has an adhesive for adhesively bonding to the honeycomb cores only in a region of the webs of the honeycomb cores.

First claim

What is claimed is:

1. A honeycomb core construction for a of a motor vehicle component, the honeycomb core construction comprising:
at least two honeycomb cores including a first honeycomb core having first honeycomb webs and a second honeycomb core having second honeycomb webs, wherein the at least two honeycomb cores are dissimilar from each other in terms of orientation such that, in relation to a surface of the component formed by the honeycomb core construction, the first honeycomb webs have a first web orientation that is 90 degrees whereas the second honeycomb webs have a web orientation that is not 90 degrees; and
a connection layer having a gas-permeable structure that is disposed between the first honeycomb core and the second honeycomb core, the connection layer having an adhesive on both sides thereof to adhesively bond the connection layer to the first honeycomb core and the second honeycomb core only at ends of the first honeycomb webs and the second honeycomb webs.

2. A honeycomb core construction for a motor vehicle component, comprising:
at least two honeycomb cores including a first honeycomb core having first honeycomb webs and a second honeycomb core having second honeycomb webs, wherein the at least two honeycomb cores are dissimilar from each other in terms of orientation such that, in relation to a surface of the component formed by the honeycomb core construction, the first honeycomb webs have a first web orientation that is 90 degrees whereas the second honeycomb webs have a web orientation that is not 90 degrees; and
an intermediate connection layer arranged between the first honeycomb core and the second honeycomb core, the intermediate connection layer having a gas-permeable structure to facilitate an exchange of air and an equalization of pressure between the first honeycomb core and the second honeycomb core, and also an adhesive on both sides thereof to adhesively bond the intermediate connection layer to the first honeycomb core and the second honeycomb core only at ends of the first honeycomb webs and the second honeycomb webs.

3. A honeycomb core construction for a motor vehicle body, comprising:
a first honeycomb core having first honeycomb webs;
a second honeycomb core having second honeycomb webs, wherein the second honeycomb core is dissimilar from the first honeycomb core in terms of orientation such that, in relation to a surface of the component formed by the honeycomb core construction, the first honeycomb webs have a first web orientation that is 90 degrees whereas the second honeycomb webs have a web orientation that is not 90 degrees; and
an intermediate, gas-permeable connection layer arranged between the first honeycomb core and the second honeycomb core to facilitate an exchange of air and an equalization of pressure between the first honeycomb core and the second honeycomb core, the intermediate, gas-permeable connection layer having an adhesive on both sides thereof to adhesively bond the intermediate, gas-permeable connection layer on a first side to web ends of the first honeycomb core and on a second side to web ends of the second honeycomb core.

4. The honeycomb core construction for a motor vehicle component of claim 1 , wherein the at least two honeycomb cores are dissimilar from each other such that, in certain zones of the honeycomb core construction, the ends of the first honeycomb webs that face away from the connection layer, are compressed, whereas the ends of the second honeycomb webs that face the connection layer, are not compressed.

5. The honeycomb core construction for a motor vehicle component of claim 2 , wherein the at least two honeycomb cores are dissimilar from each other such that, in certain zones of the honeycomb core construction, the ends of the first honeycomb webs that face away from the connection layer, are compressed, whereas the ends of the second honeycomb webs that face the connection layer, are not compressed.

6. The honeycomb core construction for a motor vehicle body of claim 3 , wherein the second honeycomb core is dissimilar from the first honeycomb core such that, in certain zones of the honeycomb core construction, the ends of the first honeycomb webs that face away from the connection layer, are compressed, whereas the ends of the second honeycomb webs that face the connection layer, are not compressed.

7. The honeycomb core construction for a motor vehicle component of claim 1 , wherein the connection layer comprises a fiber material.

8. The honeycomb core construction for a motor vehicle component of claim 2 , wherein the connection layer comprises a fiber material.

9. The honeycomb core construction for a motor vehicle body of claim 3 , wherein the connection layer comprises a fiber material.

10. The honeycomb core construction for a motor vehicle component of claim 1 , wherein the at least two honeycomb cores comprises paper cores, or cores from plastics, metal, wood, or foam.

11. The honeycomb core construction for a motor vehicle component of claim 2 , wherein the at least two honeycomb cores comprises paper cores, or cores from plastics, metal, wood, or foam.

12. The honeycomb core construction for a motor vehicle body of claim 3 , wherein the at least two honeycomb cores comprises paper cores, or cores from plastics, metal, wood, or foam.
