FIELD: mechanical testing of composite materials.
SUBSTANCE: method comprises steps of upsetting cylindrical sample between flat mutually parallel plates; using sample having concentric protruded shoulders on end surfaces; measuring effort of press at upsetting; fixing effort of press at time moment of tearing outer annular layer in the form of cylindrical envelope from central part of sample; calculating adhesion strength according to value of measured effort referred to tearing off surface area of outer annular layer from central part of sample.
EFFECT: possibility for determining adhesion strength of composite materials with formed fibrous structure.
