A sandwich-type, composite component such as a motor vehicle component and unitary structural assembly utilizing same are provided. The component has a sealed, moisture-resistant, A-surface edge. The component includes a first outer layer having an A-surface, a second outer layer having a B-surface and a core positioned between the outer layers. The core has a large number of cavities. The outer layers are bonded to the core by press molding. An edge portion of the component is locally crushed by the press molding so that the layers are bonded together to form the sealed, moisture-resistant, A-surface edge.

An assembly comprising: a component having a bottom layer and an outer peripheral side wall; anda sandwich-type, composite motor vehicle component having a sealed, moisture-resistant, A-surface edge, the component including: a first reinforced thermoplastic skin having an A-surface to display in an interior of the vehicle;a second reinforced thermoplastic skin having a B-surface; anda thermoplastic cellular core positioned between the first skin and the second skin and having a plurality of cavities wherein the skins are bonded to the core by press molding, and wherein an outer peripheral edge portion of the component is locally crushed by the press molding so that the skins are bonded together to form the sealed, moisture-resistant, A-surface edge for display in the interior of the vehicle and wherein the outer peripheral side wall is spaced inwardly from the outer peripheral edge portion. 12. The component as claimed in claim 11, wherein the skins are chemically bonded together at the periphery of the component to hermetically seal the A-surface edge. 13. The component as claimed in claim 12, wherein an end face of one of the skins is bonded to the other one of the skins. 14. The component as claimed in claim 11, wherein the skins are reinforced thermoplastic skins. 15. The component as claimed in claim 14, wherein each of the skins is fiber reinforced. 16. The component as claimed in claim 11, wherein the cellular core is a honeycomb core. 17. A unitary structural assembly comprising: a component having a bottom layer and an outer peripheral side wall; anda sandwich-type, composite panel having a sealed, moisture-resistant, A-surface edge, the panel including: a first outer layer bonded to a lower surface of the bottom layer;a second outer layer; anda core positioned between the first outer layer and the second outer layer and having a plurality of cavities wherein the outer layers are bonded to the core by press molding, and wherein an outer peripheral edge portion of the panel is locally crushed by the press molding so that the outer layers are bonded together to form the sealed, moisture-resistant, A-surface edge and wherein the outer peripheral side wall is spaced inwardly from the outer peripheral edge portion. 18. The assembly as claimed in claim 17, wherein the outer layers are chemically bonded together at the periphery of the panel to hermetically seal the A-surface edge. 19. The assembly as claimed in claim 18, wherein an end face of one of the outer layers is bonded to the other one of the outer layers. 20. The assembly as claimed in claim 17, wherein the side wall is hollow.
