The high-pressure force-network technology – an example of the research-based invention

　　The new generation sound insulation is presented that exceeds everything that currently exists on the market in this field by at least 3 to 10 TIMES! Its functionality is based on a completely new physical principle the so called the “force-networks technology”. Insulation can be made of any (waste) granular material, including metals. In this case, we get a unique sound insulation that is thermally and electrically conductive. The new insulation is applicable in all forms of transportation, industrial systems and construction.

　　The technological breakthrough is based on the scientific realization that the formation of a “force-network” – a set of pairs of forces (3NZ) – is the most effective dissipative mechanism that exists in nature. The invention relates to the process of forming the optimal size of a network of forces created by complex interactions of solid particles in a granular system. Accordingly, the sound insulation element consists of granular particles and a porous support structure that defines the shape of the insulation. It was found that the amount of dissipated energy is proportional to the size of the force network (number of pairs of forces), which can be described by the “flow index” of granular materials measured with our newly developed measuring system called “GFA analyzer”. The largest network of forces is obtained in the case of a multimodal granular particles size distribution. The latter can be predicted by the Knauss-Emri model, which was originally developed for modelling nonlinear time-dependent behavior of polymeric materials. It was surprising to find that the behavior of granular materials on the micro-macro scale and the behavior of polymers on the molecular scale can be described by the very same mathematical model if the mechanical spectrum belonging to the selected molar mass distribution is replaced by the normalized granular particle size distribution.
