Abstract Details

2008, Master of Science, University of Akron, Mechanical Engineering.
Insulation polymers are not well characterized for their mechanical properties particularly in terms of fatigue strains. This research aims to examine the durability and fatigue lives of insulation polymers, viz., (1) Polyvinyl Chloride (PVC), (2) Crosslinked Polyethylene (XLPE) and (3) Polyphenylene Ether (PPE) under selected strain and temperature ranges. The tensile properties of these materials were measured using an Instron testing machine at constantand controlled loading rates. Fatigue tests were performed at three selected temperatures: -40 °C, 25 °C and 65 °C to characterize the temperature effects on fatigue life. From the tensile test results, it was observed that PVC and XLPE tend to be more ductile and exhibits more elongation prior to breaking, while PPE exhibits brittle behavior. When the loading rate is increased, there was an improvement in the tensile strength of PPE and elastic modulus of PPE and PVC. The durability of XLPE under tensile fatigue testing was largest, followed by PVC and PPE. The fatigue life of PVC and XLPE decreased drastically at -40 °C and demonstrated a rapid increase at 65 °C compared to fatigue life at room temperature. This trend was not observed in PPE where the fatigue life showed improvement at both lower and higher temperatures.
