Abstract

The invention relates to an edge material for panels, the edge material being constructed from a plurality of bonded layers. The edge material comprises a first layer, which is non-metallic, and a core layer, which is made of at least one metal layer. The edge material also comprises a second layer, which is non-metallic. Furthermore, the invention relates to a corresponding sandwich panel and to a corresponding cover layer for panels.

5 . The edge material according to claim 1 ,
wherein each metal layer of the at least one metal layer consists of aluminum or an aluminum base alloy.

6 . The edge material according to claim 1 ,
wherein:
(i) the first layer consists of a composite material;
(ii) the second layer consists of a composite material; or
(iii) the first layer and the second layer consist of a composite material, and
wherein the composite material has a percentage by mass of phenolic resin of at least 20%.

7 . The edge material according to claim 1 ,
wherein:
(i) a metal or non-metal decorative layer is arranged on the first layer;
(ii) a metal or non-metal decorative layer is arranged on the second layer; or
(iii) a first metal or non-metal decorative layer is arranged on the first layer and a second metal or non-metal decorative layer is arranged on the second layer.

8 . A sandwich panel, comprising:
a first cover ply, wherein the first cover ply is made of a first cover material; a second cover ply, wherein the second cover ply is made of a second cover material; a core material arranged between the first cover material of the first cover ply and the second cover material of the second cover ply; and at least one side edge, wherein each side edge of the at least one side edge includes:
a first cover edge of the first cover ply;
a second cover edge of the second cover ply; and
a core edge of the core material that runs between the first cover edge of the first cover ply and the second cover edge of the second cover ply; and
an edge material according to claim 1 , wherein the edge material according to claim 1 is applied or bonded to a first side edge of-the at least one side edge such that at least a first core edge of the core material of the first side edge of the at least one side edge is covered by the edge material according to claim 1 .

9 . The sandwich panel according to claim 8 ,
wherein:
(i) the first cover material is the edge material according to claim 1 ;
(ii) the second cover material is the edge material according to claim 1 ; or
(iii) the first cover material and the second cover material are the edge material according to claim 1 .

10 . A cover layer for panels,
wherein the cover layer is made of an edge material according to claim 1 .

11 . The sandwich panel according to claim 8 , further comprising:
a first cover layer, wherein the first cover layer covers the first cover ply, and wherein the cover layer is made of the edge material according to claim 1 .

12 . The edge material according to claim 1 ,
wherein the core layer is made of a first metal layer and a second metal layer, wherein the first metal layer and the second metal layer are bonded together, wherein the edge material has a material thickness between 0.3 mm and 3.0 mm, and wherein each metal layer of the at least one metal layer has a thickness between 0.1 mm and 0.5 mm.

13 . The edge material according to claim 12 ,
wherein each metal layer of the at least one metal layer consists of aluminum or an aluminum base alloy, and wherein:
(i) the first layer consists of a composite material;
(ii) the second layer consists of a composite material; or
(iii) the first layer and the second layer consist of a composite material, and
wherein the composite material has a percentage by mass of phenolic resin of at least 20%.

14 . A sandwich panel, comprising:
a first cover ply, wherein the first cover ply is made of a first cover material; a second cover ply, wherein the second cover ply is made of a second cover material; a core material arranged between the first cover material of the first cover ply and the second cover material of the second cover ply; at least one side edge, wherein each side edge of the at least one side edge includes:
a first cover edge of the first cover ply;
a second cover edge of the second cover ply; and
a core edge of the core material that runs between the first cover edge of the first cover ply and the second cover edge of the second cover ply; and
an edge material, wherein the edge material is applied or bonded to a first side edge of the at least one side edge such that at least a first core edge of the core material of the first side edge of the at least one side edge is covered by the edge material, and wherein the edge material comprises:
a first layer,
wherein the first layer is non-metallic;
a core layer,
wherein the core layer is made of at least one metal layer; and
a second layer,
wherein the second layer is non-metallic, and
wherein the core layer is arranged between the first layer and the second layer.

15 . The sandwich panel according to claim 14 ,
wherein the core layer is made of a first metal layer and a second metal layer, wherein the first metal layer and the second metal layer are bonded together, wherein the edge material has a material thickness between 0.3 mm and 3.0 mm, and wherein each metal layer of the at least one metal layer has a thickness between 0.1 mm and 0.5 mm.
