APPARATUS FOR DETERMINING COMPLEX OF THERMOPHYSICAL CHARACTERISTICS OF COMPOSITE MATERIALS Russian patent published in 2021 - IPC G01N25/20 

FIELD: measuring.

SUBSTANCE: invention relates to the field of thermophysical studies, determining of the complex of thermophysical characteristics of composite structural and heat engineering materials on semi-cylindrical samples. The apparatus consists of a base, movable and immovable pressure plates of the heating element, a semi-cylindrical heating element with an increased thickness in the areas of attachment of the heating element, electrical insulating plates, tensioning units of the heating element, a semi-cylindrical sample installed on the inner surface of the heating element, a control thermocouple, thermocouples installed on the surface and inside the sample, protective heat-insulating elements with non-stationary heat flow sensors installed therein, thermocouples installed in the heat flow sensors, conductors installed on the heating element, protective heat-insulating elements of the side surfaces of the samples, lower and upper units for suspension of the sample in the apparatus.

EFFECT: possibility of determining and improvement in the accuracy of determining the complex of thermophysical characteristics of the examined materials on semi-cylindrical samples.
