The paper presents an improved method of experimental and computational studies of vibratory condition of the composite constructions with structural defects such as local fibrations. With the proposed approach it is possible to determine the size of the defect and its influence on the inherent forms and structure vibration frequency. In our work we demonstrate practical application of the technique studying the vibration characteristics of the feathering propeller blades with defective structure of the material.
