performance, which is connected to differences in mechanical properties of these materials as well as in fracture mechanisms characteristic for the considered material combinations within the hybrid composites. The results acquired from temperature measurements were validated with AE due to its high sensitivity to damage accumulation. The results for both approaches demonstrated high consistency, which justifies the validity of the critical self-heating temperature value as an indicator of a fatigue strength.
