Patent ID: 6967000

Claim:
A method for the fabrication of multilayer products comprising: joining a plurality of different layers with one another to form a multilayer product via polymeric binder layers; wherein the layers, inside a gas-impervious bag that is depressurized relative to an ambient atmosphere, are subjected to a compressive pressure higher than that of the ambient atmosphere while the various layers are joined into a unified product, wherein the ambient atmospheric pressure acting upon the outside of said bag is absorbed as a composite pressure load by a material having a first surface that is larger in area than the surface area of the multilayer product; wherein said material has a second surface opposite the first surface to transfer said composite pressure load to the layers of the multilayer product to be fabricated confronting said second surface; wherein the layers forming the multilayer product are compressed at a pressure higher than the ambient atmospheric pressure; wherein said composite pressure load is used to compress the multilayer product to be fabricated between said second surface and a fixed counter-die; and wherein the combined total pressure load on the first surface is distributed in a plurality of directions through the use of a wedge effect between an element connected to and axially displaced by said first surface and other elements that interwork therewith.
