FIELD: construction; measurement. ^ SUBSTANCE: method is testing of thermal properties of multilayered constructional structure. Method consists in that the thermal energy source (laser) and two thermo-receivers are used, one of which is focused in a point of a heat impact of a source, and another - in a point of a surface of the outer layer, being from the centre of a heating stain on the distance equal to a thickness of the first layer, the greatest possible capacity of a heat impact is defined, then capacity of thermic impulses is defined for the first and second set value of superfluous temperature accordingly on the first and the second set distance from the heating point smaller, than a thickness of the first (or the second) layer, then, using the received measuring results, thermal properties of outer layers of a structure are defined, and for definition of thermal properties of an inside layer of a structure the heat impact by a disk thermal radiator is carried out, the size of a heat flux is registered by means of the detecting device, the temperature is taken in points located accordingly under a disk thermal radiator and on a contact surface of the detecting device of a heat flux. ^ EFFECT: definition accuracy increasing of thermal properties of multilayered structures. ^ 3 dwg |
