Abstract
Process for the production of a composite sheet (90) comprising a cellular core (41) and at least one outer layer (42) by bonding the outer layer (42) to the cellular core (41), for example with the aid of an adhesive film (84) under pressure and at elevated temperature, where the adhesive film (84) may initially extend over the entire surface and breaks up in the region of the honeycomb interior under the action of heat and on exposure to a gaseous medium, concentrating at the points of contact between the cellular core (41) and the outer layer (42). The outer layer (42) itself has an adhesive layer or an adhesive film (83) on the side facing the cellular core. The outer layer bonds to the cellular core under pressure and at elevated temperature.
