Abstract
Complex experimental studies on the effect of temperature, static load and electron irradiation on the thermomechanical properties of polytetrafluoroethylene material were carried out. The obtained data of the dependence ɛ on t confirms the presence of phase transitions in this film. Irradiation significantly affects the dependences ɛ(t) and ɛ(ơ). Polytetrafluoroethylene material loses plasticity after electron irradiation, deformation (compared to non-irradiated material) by ~170 %, which is associated with the destruction of all chains. The experimental dependence ɛ on ơ for both non-irradiated and irradiated material is satisfactorily described in the cascade probabilistic model.
