US Patent 7851069 Heat shield with integral attachment flanges

An aluminum layered heat shield assembly (30) includes a pair of spaced metallic facing sheets (32) fabricated from an aluminum composition. In the interstitial space between the facing sheets (32), a perforated steel core (34) is formed in the general shape of a zigzag baffle with segments that adjoin and maintain a generally consistent spacing. The perforated steel core (34) is fabricated with non-perforated flanges (42) which project outwardly from between the aluminum facing sheets (32) to establish extensions for attachment to a supporting structure.
