Abstract

Effect of different fluids on mechanical properties of a U- liner R.M. Bakeer,* M.E. Barber,* R. Subramanian," I.C. Mandich* " Department of Civil and Environmental Engineerig, Tulane University, New Orleans, Louisiana 70118, USA * Delta US Engineering, 101 Teal Street, St. Rose, Louisiana ABSTRACT Tension tests were performed on dog-bone shaped samples cut from a polyethylene U-liner to evaluate the effects of exposure to various petroleum- based products on material characteristics. Material properties of the liner examined were weight, tensile strength, elongation, required time for yield and elasticity modulus. Samples were soaked in alcohol, diesel fuel, gasoline, jet fuel or kerosene for durations of 56, 84 and 112 days before testing. Additional samples were exposed to natural day light for 56 days to examine the effect of ultra-violet rays (UV). Virgin samples were used as control samples for comparison. Tensile properties of the liner material were sli
