An implementation of an accelerated testing methodology to obtain static, creep and fatigue master curves of a T300/913 unidirectional composite material

Abstract

This study focuses on the prediction of long term residual strength, creep and fatigue characteristics of T300/913 unidirectional composite material. Both tensile and three point bending specimens were tested. The relation between time and temperature was established, and residual strength, creep and fatigue master-curves were determined. These curves were compared to test results at different elevated temperatures, applied strain rates and cyclic loading frequencies. From the results presented in this paper, it can be readily concluded that the time-temperature superposition principle indeed holds for creep, residual strength and fatigue behavior of the T300/913 unidirectional tape.
