Abstract : The results of testing the mechanical properties of glass textolite of type KAST under surface heating are presented. The tests were conducted in conditions of pure shear on specimens of dimensions 11 x 11 x 150 mm. Heat currents used varied in the range of 840-2100 kv/sq m. One-sided surface heating was performed by generating an electrical current through the carbonized layer of the tested glass plastic. Factors identified as affecting the bearing capacity of a specimen at a given instant are: (1) the depth of the zone of material with the reference (base) properties, (2) the variation of the elastic constants in the zone of the base material under increasing temperature in that zone, (3) the strength of zone of pyrolysis and of the carbonized zone, their dimensions and position relative to the neutral axis under shear, (4) thermal stress in the pyrolysis zone and in the carbonized layers.
