The stress-strain state at the tip of a crack in a discretely reinforced quasi-isotropic carbon-carbon composite material (CCCM) is studied. The stress intensity factor J 1c and the J-integral are evaluated in accordance with domestic methods and international standards. The distribution of the fields of displacements and strains on the surface of the specimens is determined by the method of numerical correlation of digital images using a VIC-D system. The applicability of different criteria to evaluation of the fracture toughness of CCCM of type TERMAR is determined.
