In this article the problems occurring during the operation of composite materials are discussed. A summary of information about composite materials, their application features is given. Important aspects of the diagnosis of composite materials are considered. Some methods for finding defects in composite materials are proposed. An experimental study showed no dependence of the oscillation frequency on the occurrence of defects, but clearly demonstrated its change from the location of the defect. The proposed defect control method shows the possibility of creating a system for controlling delamination in composite materials on the basis of vibration processes and to determine its main parameters.
