Gas-Structure Element as the Main Morphological Unit

It is now apparent that the classification of porous materials which was based on the cell (pore) and type of communication between cells (pores), as the main morphologi- 

On the basis of the GSE concept gas-filled materials may be divided into the following types  

microballon or syntactic foams, the GSE of which consists of a gaseous phase, included in a spherical shell of monolithic material, and a solid phase composed of these shells (of polymeric or mineral nature) and of the interspherical space filled with polymer  

capillary of fibrous plastics, whose GSE consist of a gaseous phase included in an anisometrically shaped volume and of a polymeric binder
