Patent Images
1. A composite heat-shielded component, comprising:
- (a) a metal sheet, the metal sheet including protrusions extending away from a first broad surface of the metallic layer, the protrusions being spaced from one another to define a pattern of plain polygonal areas on the sheet; and
(b) a blow-molded layer attached in situ to the metal sheet, wherein the blow-molded layer is molded in-situ in surrounding relationship with the protrusions to attach the metal sheet to the blow-molded layer and forms a plurality of polygonal recessed areas defining a plurality of air gap pockets between the blow-molded layer and the metallic layer and surrounded by the protrusions.

Abstract
The present invention relates to a method for making a shielded automobile component and the shielded automobile component itself. The component includes a composite formed of a metal sheet which includes protrusions which extend from a surface of the metal sheet and a blow-molded thermoplastic layer formed around the protrusions which fixes the blow-molded layer to the metal sheet during the molding process. The protrusions on the metal sheet define plain polygonal areas which are free of protrusions.
