Effect of γ radiation on the long-term strength of polyethylene terephthalate

  • Published:
Polymer Mechanics Aims and scope

Abstract

By analyzing the results of a study of the long-term strength and isometric heating diagrams of polyethylene terephthalate exposed to γ radiation it has been established that irradiation leads to a decrease in the short-time and long-term strength of the polymer and to the misorientation of its structural elements. The coefficient γ in the long-term strength equation increases with the radiation dose, while U0 varies along a curve with a maximum at small doses.
