ABSTRACT:
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.
