Abstract (en)
[origin: NL1024505C2] The panel (1) is made from layers of paper or card(board), each of which comprises a corrugated layer with a flat face layer on one side. The layers are bonded together via adhesive applied to the tips of the pleats (6) in the corrugated layer. The panel is impregnated, preferably with a resin, and contains at least one reinforcing layer (3) which has a greater elasticity modulus than the paper or card(board) layers and is bonded on one side to a paper or card(board) layer using adhesive.
