Relaxation properties of structural heat-resistant polymers over a wide temperature range

  • Published:
Mechanics of Composite Materials Aims and scope

Conclusions

For heat-resistant polymers differing in structure (polybenzoxazole, polyoxadiazole, and polyimide), the viscoelastic properties have been studied under conditions of creep and relaxation over a broad range of temperatures, from −150° to 400°C. In the region of temperatures of the glassy state, relaxation transitions have been detected, separating this region into subregions with different rates of the relaxation processes. The mechanical capability of these polymers has been determined under isothermal and nonisothermal conditions, with an accounting for relaxation processes.
