Abstract
A composite panel comprising a core (12) and at least one outer sheet (14) which is adhesively bonded to the core is such that the composite panel (10) is shape-formed creating at least one radius of bending (24b) in the outer layer (14). The core (12) has a cellular structure and is bonded to the outer layer (14) at least by one visco-elastic adhesive layer (16) applied over the entire inner surface of the outer layer (14). The combination of the honeycomb structure of the core and the adhesive layer with the mentioned properties attaching the core to the outer sheet leads to a composite panel that may be shaped quickly and at favorable cost, without the outer layers being damaged or the stength being significantly reduced. As a result of the large area visco-elastic bonding a higher resistance to delamination, debonding due to vibration, corrosion and moisture is achieved.
