Abstract: An example method for manufacturing a multicellular structure for acoustic damping is described that includes applying a porogen material to a solid support, inserting a multicellular frame into the solid support and through the porogen material so as to fill cells of the multicellular frame with the porogen material, fusing the porogen material, removing the multicellular frame from the solid support, and the multicellular frame contains a suspended fused porogen network attached to walls of the cells of the multicellular frame. The method also includes applying a solution to the suspended fused porogen network in the cells of the multicellular frame to percolate the suspended fused porogen network, curing the solution, and removing the suspended fused porogen network from the multicellular frame resulting in porous septum membranes of the cured solution in cells of the multicellular frame.

Abstract: A fabric coated or impregnated with an elastomeric material may include a polyurethane dispersion layer combined with a sealant. The fabric may be applied in such a fashion so as to enable the elimination of solvent or fluid that is associated with the elastomer. The polyurethane dispersion layer generally comprises an elastomeric material dispersed or dissolved in a liquid medium, such as, but not limited to, water. At the same time, the integrity of the elastomeric composite which is formed from the dispersion and sealant layers may be maintained in order to minimize the presence of air voids and pockets. It has thus been realized that in doing so the performance of the self-sealing volume is dramatically improved. This method of construction usually may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume.
