225 高分子材料(PEEK, PEI, POM)のガラス転移領域におけるクリープ挙動(OS 高分子/高分子基複合材料(4))

抄録

We experimented creep tests for polyetherethylene(PEEK) and polyetherimide(PEI) and polyoxymethylene(POM) at constant applied stress. The creep curves of PEEK and POM depended on the temperature and applied stress. The lives of the polymers were expressed by the following equation. The values of n depend on the temperature. They were reduced at high temperatures.
