Statement of the problem. Various methods of accelerated testing are used to determine the endurance of polymer composite materials. One of these methods is the temperature method which has its own limitations. Thus the possibility of its application for epoxy polymer materials should be established.Results. The article suggests a formula for identifying the value of the fatigue life of an epoxy composite material. The reliability of the values calculated using this formula is experimentally established. It is proved that the intensity of the temperature increase depends on the loading speed. Conclusions. The reliability of the calculations according to the suggested formula for calculating the fatigue life indicators is confirmed by comparing the results with the experimental data, the values are quite closely correlated allowing the formula to be used while calculating the endurance for samples made of epoxy composite.
