A layered panel structure featuring a first layer formed of non-thermoformable material, having opposite faces, a thickness T as measured between its opposite faces, and an effective layer density d, and a second layer formed of thermoformable material having opposite faces, with one face in the second layer being thermally bonded to one face in the first layer, and with the second layer having a thickness t, as measured between its opposite faces which is smaller than T, and an effective layer density D which is greater than d. The thermal bond between the layers is formed, during thermoforming of the panel structure, by a melt and flow of resin contained in the thermoformable layer material.

We claim: 1. A layered, generally planar panel structure comprising a first layer of non-thermoformable material formed of one of balsa wood, urethane foam, PVC foam, polyester foam, honeycomb plastics, honeycomb metals, and corrugated wood, having a thickness T and a density d, and possessing opposite faces, a second layer of thermoformable plastic material having another thickness t which is less than said thickness T, and another density D which is greater than said density d, and also possessing opposite faces, and a thermal-compression, inter-material-transition bond structurally featuring a prior-molten flow of plastic material received from said thermoformable plastic material joining one face in the first layer with one face in the second layer. 2. The panel structure of claim 1, wherein said thermoformable material takes the form of a polypropylene-resin-encapsulated strand material including strands made of one of glass, E-glass, S-glass and carbon fibre.
