The invention relates to method for the production of a multi-layered sandwich-lightweight building board (2). According to the invention, a thermoplastic supporting core (3) is connected to at least one cover layer (4) made of a plate-shaped element. The cover layer (4) is made of a fibre material (6) in the form of fibres, fibre tissue, non-woven and rovings or similar arrangement and liquid thermoplastic material which are guided together and the liquid thermoplastic material is rolled into or walked into the fibre material (6) under pressure. Said cover layer (4) is subsequently guided to the supporting core (3) and is thermoplastically connected to the supporting core (3) with the aid of the liquid thermoplastic material thereof. |
