... without the limit value of the overall structure being exceeded. It is also known that different manufacturing processes, for example the process for manufacturing a closed sandwich panel, can result in completely different heat release values although identical materials are used.

... Equipment parts will only be mentioned in passing. A look at the interior of today's wide-body aircraft shows that more than 80 percent of the passenger cabin interior consists of sandwich structures mainly comprising f~bre-reinforced phenolic resin top layers with Nomex~ honeycomb cores and a decoration of decorative laminates, simple PVF foil, textiles, or varnishes.

... Curved Sandwich Structures The following components are typical: window panels, ceiling panels, stowage bins (parts) , stowage bin doors, and door failings.

... O Textiles used for decoration are mostly applied by pressure-sensitive adhesives or by dispersion adhesives curing at room temperature; the procedure corresponds to the one used for the application of decorative foils. Monolithic Here composites, with thermosetting or thermoplastic matrix systems, as well as thermoplastic thermoformed parts and also injection moulding parts are used in addition to sandwich structures.

... Developments on the interior sector considered here will focus on the large-area sandwich structures of sidewall panels, ceiling panels, stowage bins, partitions, and walls for galleys and lavatories due to their high share in the interior. The reduction of the flow times for manufacture and the significant simplification and mechanization of assembly sequences offer an important potential for the reduction of manufacturing costs.

... · Simplified designs and integral manufacturing techniques permit, for example, the manufacture of the essential body of a stowage bin from a flat semifinished sandwich product by special folding technique. In the area of monolithic components, alternative technologies such as the resin transfer moulding or the resin film infusion process can also be reviewed for their cost reduction potential.

... The task of balancing boundary conditions and effects that are partly contradictory, however, is becoming more complex instead of simpler. All participants must therefore cooperate closely to meet this challenge.
