Abstract
Experimental studies on the effect of static stress (σ), electron dose (D) and temperature (T) on the deformation (α) in time (t) of unirradiated and irradiated fluoroplastic were carried out. The combined effect of electron irradiation and stress leads to a significant increase in the strain up to rupture. With mechanical effects, with an increase in the absorbed dose, the stress and relative elongation of the fluoroplastic decrease, which is associated with the degradation of the main circuits of the fluoroplastic. Irradiation of polytetrafluoroethylene during thermomechanical testing leads to a decrease in deformation compared to unirradiated material.
