ABSTRACT:
A porous composite structure for controlling of gas flow therethrough. The porous composite structure includes a first porous element formed from a sheet having a plurality of perforations with a first total predetermined cross-sectional area. A second porous element formed from a perforated sheet having a second total predetermined perforation cross-sectional area is disposed parallel to the first porous element and spaced a predetermined distance therefrom. At least one intermediate porous element is interposed the first porous element and the second porous element. The intermediate porous element has a total predetermined cross-sectional pore area which is less than the first and second total predetermined cross-sectional areas. Each of the porous elements are bonded to adjacent porous elements to form an integral structure, whereby the intermediate porous element regulates the flow of gas through the porous composite structure while the first and second porous elements mechanically strengthen the porous composite structure. A method of producing the porous element is also disclosed.
