final stages of loading. The total number of low-frequency signals recorded on the plate is significantly higher than on the concrete surface. Thus, low-frequency AE signals recorded on the surface of the composite canvas carry significant information about the deformation processes occurring at the boundary of concrete and composite. A sharp increase in the emission of signals of this type may indicate the activation of delamination processes in the contact zone between concrete and composite, as well as the appearance of various types of defects in the composite. The conducted experimental study demonstrates that the AE control method is very promising in terms of the ability to control deformation processes at the interface between concrete and composite. This approach can be used to organize continuous monitoring systems for structures reinforced with composite elements.
