The FKM rubber was selected as a perspective material since it is known by its resistances against high temperatures and against aggressive chemicals. As a study case, the five-blade bundle linked by wedge-form rubber elements imposed in the head interspaces of the neighbouring blades was chosen. Thermo-mechanical effect on the dynamics of the bundle was investigated numerically and experimentally and a good agreement was achieved in modal characteristics of both approaches. The results of the study show that although the material damping markedly decreases at higher temperatures around 150 degrees C with respect to a room temperature, the damping capacity of the FKM elements remains still relatively high with comparison to the interblade structural damping as a result of dry friction.
