FIELD: composite materials.
SUBSTANCE: invention relates to determination and analysis of strength properties of composite materials operating at simultaneous action of normal and tangential stresses. Proposed device comprises four semi-circular discs connected in pairs to recapitulate test piece in central part on one side with cutout. To fix the sample, metal corrugated gaskets are used with clamping screws installed on semicircular discs in the sample attachment area, thus ensuring adhesion of the analyzed sample to the installation.
EFFECT: reduction of labor costs in preparation of study samples, expansion of range of thickness of analyzed samples and expansion of structural variety of devices for investigation of strength of material at complex loading.
