Method for the manufacturing of a cladding element for a passenger cabin of a vehicle
A method for manufacturing a cladding element for a passenger cabin of a vehicle is provided. A first layer is introduced into a forming shell. A support layer is provided onto the first layer, such that the first layer extends beyond an edge of the support layer. An elastic material strip is provided onto a portion of the first layer hat extends beyond the support layer, such that the material strip is flush with the edge of the support layer. A second layer is provided onto the support layer, such that a portion of the second layer extends beyond the edge of the support layer and is superimposed on the material strip. The forming shell is closed and a pressure is exerted on the layer arrangement accommodated in the forming shell at a temperature between 50° C. to 100° C., to form a sandwich structure.
1. A method for manufacturing a cladding element for a passenger cabin of a vehicle, the method comprising:
introducing a first layer into a forming shell, wherein the first layer comprises first fibres and is impregnated with a resin,
providing a support layer onto the first layer, such that the first layer extends beyond at least one edge of the support layer, wherein the support layer is reinforced with second fibres,
providing an elastic material strip onto a portion of the first layer that extends beyond the support layer, such that the material strip is flush with the edge of the support layer,
providing a second layer onto the support layer, such that a portion of the second layer extends beyond the edge of the support layer and is superimposed on the material strip, wherein the second layer comprises the first fibres and is impregnated with the resin, and
closing the forming shell and exerting a pressure on the layer arrangement accommodated in the forming shell, at a temperature in a range of 50° C. to 100° C., such that a sandwich structure is formed.
2. The method according to claim 1 , wherein said vehicle is a land vehicle, an aircraft or a watercraft.
3. The method according to claim 1 , wherein the forming shell is closed by a film wrapping around the forming shell and the pressure is generated through vacuum.
4. The method according to claim 1 , wherein the resin comprises a phenolic resin which is cured at a temperature of 70° C. to 90° C. during pressing.
5. The method according to claim 1 , wherein, during pressing, the material strip is plastically deformed to a shape which is predefined by the forming shell.
6. The method according to claim 1 , wherein a thickness of the material strip reduces towards a free edge of the material strip.
7. The method according to claim 5 , wherein the material strip has a default compression zone which is formed by at least one recess, said at least one recess being substantially parallel to the free edge of the material strip.
8. The method according to claim 1 , wherein the material strip is formed from a foam.
9. The method according to claim 8 , wherein said foam is a closed-cell foam.
10. The method according to claim 1 , wherein the material strip is manufactured from a chloroprene elastomer.
11. The method according to claim 1 , wherein the first fibres comprise at least one of glass fibres and carbon fibres.
12. The method according to claim 1 , wherein the second fibres comprise at least one of aramid fibres and carbon fibres.
13. The method according to claim 1 , wherein the support layer has a honeycomb structure and wherein the delimiting walls of the honeycombs are oriented approximately vertically to a visible side of the cladding component.
14. The method according to claim 1 , wherein a flexible layer is adhesively bonded onto the second layer of the sandwich structure and the material strip.
15. The method according to claim 14 , wherein the flexible layer is formed from an open-cell foam.
16. The method according to claim 1 , wherein a decorative layer, which covers the visible side of the cladding element, is adhesively bonded onto the sandwich structure.
17. The method according to claim 16 , wherein the decorative layer is formed from an artificial leather or from a plastic film.
18. The method according to claim 14 , wherein a decorative layer, which covers the visible side of the cladding element, is adhesively bonded onto the flexible layer.
19. The method according to claim 18 , wherein the decorative layer is formed from an artificial leather or from a plastic film.
