  • the invention provides that the middle layer is at least partially made of wood boards or laminated veneer lumber. A sufficiently high strength of the composite panel can thereby be achieved. It has been shown that the middle layer of wooden boards or laminated veneer lumber in combination with the cover sides glued flat to the middle layer results in a composite panel that has a sufficiently high load-bearing capacity, especially for interior construction.
