The enhanced sandwich structure of powder-based composite with relatively high volume fraction of powders composed of fine densified skins and periodically localized densified core-material for improving their mechanical properties and formability is presented. The structurized composites are fabricated by rolling process with the aid of a novel dynamic three-dimensional rolling technique. This methodology with various actuating phases exhibits different characteristics of forming schemes to fabricate desired structure of composites and provides assorted effects on the forming properties. Consequently, the enhanced sandwich structures of the composite sheet enable the tensile strength and the failure strain to be controllable and improved significantly. In addition, the bendability and the flowability of the composite sheets meaningfully related to their formability are greatly enhanced. (C) 2004 Kluwer Academic Publishers.
