Study of the Effect of Aging Progression on Creep Behavior of PPE Composites

Study of the Effect of Aging Progression on Creep Behavior of PPE Composites In this study, creep behavior of stainless fiber-PPE composites was analyzed in an oil environment at elevated temperatures, and the effects of physical aging on creep behavior were intensively investigated. The results showed that the creep phenomena of metal fiber-PPE composite with pre-aging treatment correlated with the Arrhenius time-temperature reciprocation law and within the aging range; time-aging time superposition also held good. Thus, prediction of short-term creep behavior for any pre-aging time was possible, based on the grand master curve of the creep compliance master curves and the shift factor for aging progression. It was clarified that a pre-aged composite can withstand higher temperatures and longer times. It was also observed that the energy of activation during creep decreased with an increase in pre-aging treatment time. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Mechanics of Time-Dependent Materials Springer Journals

Abstract

In this study, creep behavior of stainless fiber-PPE composites was analyzed in an oil environment at elevated temperatures, and the effects of physical aging on creep behavior were intensively investigated. The results showed that the creep phenomena of metal fiber-PPE composite with pre-aging treatment correlated with the Arrhenius time-temperature reciprocation law and within the aging range; time-aging time superposition also held good. Thus, prediction of short-term creep behavior for any pre-aging time was possible, based on the grand master curve of the creep compliance master curves and the shift factor for aging progression. It was clarified that a pre-aged composite can withstand higher temperatures and longer times. It was also observed that the energy of activation during creep decreased with an increase in pre-aging treatment time.
