Pressure regulated structure

This invention relates to structures, and more particularly, to a pressure regulated structure. A pressure regulated structure includes a first layer, a second layer, a non-metallic honeycomb assembly, and a vent. The honeycomb assembly is between the first layer and the second layer and includes a plurality of walls forming cells, at least some of the walls including laser-formed apertures to allow fluid communication between cells. The vent is fluidly coupled to the honeycomb assembly, wherein fluid in the cells of the honeycomb assembly may be removed through the vent to decrease pressure in the structure.
