Abstract
The temperature and frequency dependent viscoelasticity of carbon black filled rubber is investigated. Temperature sweep and frequency sweep dynamic mechanical analysis tests are performed to investigate the frequency dependent glass transition temperature and to identify the thermorheological nature of the material. The test results show that master curves of dynamical properties can be constructed by horizontal shifts along the frequency axis alone and cover a frequency range of 21 decades, verifying the material's thermorheological simplicity. This simplicity is confirmed by van Gurp–Palmen and Cole–Cole plots. Moreover, the temperature dependence of the shift factor is modelled well by both the Williams–Landel–Ferry equation and the Arrhenius equation.
