Abstract
Vacuum filled hollow alveoles embedded in an insulation material in order to arrive at a light weight insulation material using the high breakdown voltage of evacuated cavities, i.e. alveoles at a vacuum lower than the minimum of the Paschen law. Pressurized hollow alveoles embedded in an insulation material in order to arrive at a light weight insulation material using the high breakdown voltage of pressurized cavities, i.e. alveoles at a pressure higher than the minimum of the Paschen law.
Claims42
Alveole having a wall enclosing a cavity (12), wherein the wall (11) of the alveole (10) comprises pores (13) in a size allowing a gas molecule (4) to pass the wall of the alveole and hindering a polymer molecule (5) to pass from the outer to the inner of the alveole.
Insulator material comprising a matrix material (20) and a plurality of alveoles (10), wherein the alvoles are evacuated at a pressure lower than the pressure which corresponds to the minimum of the Paschen law.
