Abstract: A composite material is described. The composite material comprises a first cover sheet, a second cover sheet, and a core layer arranged between the first cover sheet and the second cover sheet, said core layer comprising a first adhesive layer in contact with the first cover sheet, a second adhesive layer in contact with the second cover sheet, and fibres which extend from the first adhesive layer to the second adhesive layer. The first cover sheet has a larger extension than the core layer and comprises at least a first edge region which is free from the core layer, wherein the first edge region extends from the outer edge of the first cover sheet to the core layer.

Abstract: Method and arrangement for manufacturing core composite layer workpieces (sandwich structures) from at least one first and at least one second cover sheet (1, 2) between which a core sheet (30) including especially short cut fibers (9) is provided, are disclosed with which a continuous and substantially break free manufacture can be conducted which leads to composite layer structures with reasonable costs. Single manufacturing parameters can specifically be varied with different embodiments so that in a relatively simple manner composite layer structures with desired physical properties can be obtained, for example with respect to their strength, stiffness, flexibility, mechanical and acoustic absorption capabilities, working properties, and so on. Composite layer structures for new applications can be manufactured as well.
