Abstract
The present invention relates to filled polymeric materials including a thermoplastic polymer and a metallic filler and to light weight composite materials, which comprise a metallic layer and a polymeric layer, the polymeric layer containing the filled polymeric material. The filled polymeric material preferably is an extruded sheet. The composite materials of the present invention may be formed using conventional stamping equipment at ambient temperatures and/or welded to other metal materials using conventional welding techniques.
