Abstract: The invention relates to a method for producing a composite panel comprising a paper honeycomb core (3) and a panel (2,2?) attached to both sides of the honeycomb core (3) in a continuous process, said method comprising the steps of producing a continuous paper honeycomb from at least one band of paper by cutting strips (12) of paper in substantially transverse direction off of the band of paper, stacking said strips (12) onto one another while being attached at various locations along the length of the strips to form the continuous honeycomb in compressed form, expanding said compressed continuous paper honeycomb and impregnating it with a curable composition (7), impregnating a first and second continuous fibre-reinforced web with said curable composition (7), or a further curable composition which chemically binds to said curable composition (7), removing entrapped air from said impregnated fibre-reinforced web, applying said first and second impregnated fibre-reinforced web against respective both sides o
