The process of creating a defective composite panel by the method of contact molding is described in detail for developing the method of non-destructive testing and analyzing the results of drilling artificially weakened sections of a carbon fiber reinforced panel. In the process of manufacturing a carbon fiber panel, defects are embedded in its structure in accordance with the template, leading to a violation of adhesion in the “fiber-binder” structure and most effectively controlled by non-destructive testing methods. Further directions of the study of the panel-sample are indicated for a detailed study of the results obtained using the method of acoustic emission.
