FIELD: measuring technology.
SUBSTANCE: invention relates to methods for determining the performance characteristics of polymer composite materials, specifically to methods for determining the durability and long-term strength of polymer composite materials under load. Essence: the sample is loaded with a constant voltage of a given value, the loaded sample is kept at a given temperature with a container with a corrosive medium placed in the middle part: the place of the greatest deflection, and the time till destruction (durability) is determined, and the specified voltage value (long-term strength) is created by loading the sample with a longitudinal bend.
EFFECT: increasing the reliability of test results and reducing their labor intensity.
