Abstract
The invention is directed at composite materials, articles including the composite materials, and methods for producing and using them. The composite material include regions that differ in one or more properties. The composite material generally includes a first metallic sheet, a second metallic sheet; one or more metallic inserts interposed between the first and second metallic sheets; and a polymeric layer (e.g., a core layer) interposed between the first and second metallic sheets. The polymeric layer preferably includes a thermoplastic polymer. Preferably, the composite material includes a first region having an insert interposed between the metallic sheets so that the first region (relative to the second region) has a high tensile strength, a high thickness, a high density, or any combination thereof.
