Investigations of three groups of samples from carbon fiber T 700 and the composite wing box of the aircraft were carried out. Samples with monolayers laying 0; 90; –45 were subjected to shock loads, which were applied at their center with a load in the form of a blunt tip weighing 0.53 kg. Loads were dumped from a height of 0,3; 0,5; 1 m per sample. Impact damage with an energy of 15 J was also applied to the upper surface of the carbon fiber wing box. Acoustic emission (AE) signals were recorded from the piezoelectric antenna sensors mounted on the wing samples and box both during the impact of the weight with the object under study and during rebounds. The locations where the shock load were applied were located and the parameters of the AE signals were analyzed. The influence of the type of monolayer laying on the process of cracking in the material of the samples arising at different energy of shock loads was determined.
