The procedure is proposed to evaluate the CFRP components damage tolerance under irregular loading in compression zone. A number of aspects of modern CFRP damage under cyclic loading are considered. The proposed procedure of evaluating the damage tolerance under combined loading in compression zone is verified. The verification demonstrated the procedure applicability as well as the recommendations were issued for the procedure parameters values.
