Abstract

A multifunctional fully integral panel system design, a unique material configuration, and a process for fabricating a net shape (or nearly net shape) panel in one production cycle. The panel may comprise a base facing (2) with an outer perimeter, a decorative film (8) applied to the exterior of the base facing (2), an aft facing (4) having an outer perimeter fused to the base facing (2), and a reinforcement core (6) disposed between the unfused portions of the base (2) and aft facings (4), which reinforcement core (6) also acts as acoustic insulation (i.e., a noise attenuator). Alternatively or additionally, a foam core or blanket (16) having thermal and/or acoustic insulation properties is attached to the external surface of the aft facing (4). The fabrication process involves the application of different heat treatments to panel components having different forming temperature or rubbery/elastic plateaus.
