摘要

<正> The temperature spectra of internal friction of polyetheretherketone （PEEK） are investigated from 130K to 250K with a multi-function torsion pendulum in the frequency range of 0.1 Hz to 5 Hz. A relaxation process

and the relation between molecular motion mechanism and the distribution characteristic are discussed. The element process of γrelaxation is found to be a disordering one.

Abstract

The temperature spectra of internal friction of polyetheretherketone （PEEK） are investigated from 130K to 250K with a multi-function torsion pendulum in the frequency range of 0.1 Hz to 5 Hz. A relaxation process

γ relaxation

appears in the temperature range of the measurement. Its relaxation time distribution in terms of a Gaussian distribution

and the relation between molecular motion mechanism and the distribution characteristic are discussed. The element process of γ relaxation is found to be a disordering one.
