Abstract

The article provides an analysis of domestic and foreign methods of mechanical testing of structural aviation composite materials and coatings on a slice. The types of cross-section fittings and their main differences are presented. The development of testing methods by instrumental indentation and scratching (sclerometry) is shown, in which destruction occurs by cutting the material with an indenter. A typical slice diagram in the coordinates «load‒displacement of the punch», diagrams of embedding and scratching with indentors, photographs of scratches without destruction and with traces of destruction on the deformable surface are presented.
