The invention describes a composite component based on a sandwich structure, composed of: (a) at least two outer layers which independently of each other comprised at least one film, sheet, fiber mat and/or foam made from metal, plastic, glass, natural material and/or carbon, and (b) a core posit
The invention describes a composite component based on a sandwich structure, composed of: (a) at least two outer layers which independently of each other comprised at least one film, sheet, fiber mat and/or foam made from metal, plastic, glass, natural material and/or carbon, and (b) a core positioned between the outer layers, made from metal, plastic, natural material and/or paper having a large number of cavities, in which a casting resin system at least partially penetrates the outer layers and the core and the outer layers are bonded to the core by press molding. The composite component is characterised in that in at least one area of the sandwich structure the outer layers are pressed together and the compressed area of the sandwich structure is encapsulated with thermoplastic polymer. Composite base on a sandwich structure are obtained by encapsulating at least one area of the two outer layers. The encapsulating area is that area of the two outer layers have been pressed together.

What is claimed is: 1. A composite component based on a sandwich structure comprising: (a) at least two outer layers each of which comprises a film, a sheet, a fiber mat and/or a foam made from metal, plastic, glass, natural material and/or carbon, and (b) a core positioned between the outer layers
What is claimed is: 1. A composite component based on a sandwich structure comprising: (a) at least two outer layers each of which comprises a film, a sheet, a fiber mat and/or a foam made from metal, plastic, glass, natural material and/or carbon, and (b) a core positioned between the outer layers which comprises metal, plastic, natural material and/or paper having a large number of cavities, in which, a casting resin system at least partially penetrates the outer layers and the core, the outer layers are bonded to the core by press molding, the outer layers of the sandwich structure are pressed together in at least one area and the resultant compressed area of the sandwich structure is encapsulated with thermoplastic polymer. 2. The composite component of claim 1 in which the core (b) has a corrugated, angled, honeycomb or foam-like structure. 3. The composite component of claim 2 in which the outer layers (a) are fiber mats. 4. The composite component of claim 1 in which the outer layers (a) are fiber mats. 5. The composite component of claim 1 in which the casting resin system is a two-component polyurethane system. 6. The composite component of claim 1 in which the outer layers are pressed together in the edge area of the sandwich structure and the compressed edge area is encapsulated with thermoplastic polymer. 7. The composite component of claim 1 in which the outer layers are pressed together at or around an opening, a bead or deformation in the sandwich structure and the compressed area is encapsulated with thermoplastic polymer. 8. The composite component of claim 1 in which the encapsulated thermoplastic polymer near the area of the outer layers that have been pressed together at least partially fills the cavities in the core in such a way that it forms an undercut. 9. The composite component of claim 1 in which the thermoplastic polymer is a non-reinforced, reinforced and/or filled polymer based on polyamide, polyester, polystyrene, acrylonitrile-butadiene-styrene, thermoplastic polyurethane, polyolefin, polycarbonate, polypropylene oxide, polysulfone, polyphenylene sulfide, polyimide, polyether ether ketone or a mixture of these polymers.
