Analysis of Visco-elastic-plastic Behaviour of Short Glass Fiber-reinforced Polyamide 66 Composite (PA66 GF30)

摘要

In this paper, the behaviour of polyamide 66 with 30% short glass fibers (PA66 GF30) is investigated using instrumented indentation technique combined with the dynamic mechanical analysis (DMA). The visco-elastic-plastic behaviour of PA66 GF30 is described by a rheological model which incorporates a spring, a plastic element and Kelvin-Voigt elements. The time-temperature superposition (TTS) principle was used to investigate the effect of time and temperature on the behaviour of PA66 GF30.
