The study aims to determine the effect of a “delamination” defect on the service life of carbon fiber reinforced polymer (CFRP) specimens and specimens that have been repaired. The tests were performed using an EHF-EV101K2-04N-1E universal testing machine, and ultrasonic flaw detection was carried out using the ELISA GMIUC002-14 complex. In the study, loading ranges were selected for cyclic tests performed for defect-free, defective and repaired specimens. The tests revealed the effect of the defect and its repair on durability of CFRP products.
