Abstract : Tests conducted with flat samples of EF-S oriented glass-reinforced plastic with an epoxy-phenol bonding agent demonstrated that in the test range of thicknesses and linear unidrectional heating rates, with uniaxial compression in the sheet plane, the relative failure load at the ends of the sample is also a single-valued function of the thermal similitude criteria -- Fo and Pd. A classification scheme is proposed which describes the effect of the composition and deformation properties of the bonding agent on the failure kinetics of AG-4S and EF-S glass-reinforced plastic samples under uniaxial compression in the sheet plane and under a unidrectional thermal effect.
