The article considers the issues of the influence of repeated thermal shock on the frictional properties of a carbon-carbon composite material. For thermal loading, the heat-pulse method was applied, in which the energy of rotating masses is absorbed by a friction couple from samples of the material being studied. The change in the friction coefficient during braking is analyzed. Based on the results of repeated braking, conclusions are drawn about the resistance of the material to thermal cyclic behaviours. Particular attention is paid to the maximum temperature that occurs on friction surfaces and the temperature change during thermal loading. The dependence of the average friction coefficient in each test on the number of loading cycles was obtained. Based on the study, the number of thermal loads at which the frictional properties of the material are stable was established.
