Abstract
This paper deals with the determination of time-temperature shift factor for viscoelastic modulus of polymer resin, which will be used for the accelerated testing of polymer composites based on the accelerated testing methodology. The creep test and dynamic viscoelastic test for epoxy resin were conducted under various temperatures. The master curves of creep compliance and storage modulus were constructed based on the time-temperature superposition principle and then time-temperature shift factor were obtained. The accurate and easy method for determination of time-temperature shift factor was discussed.
