Abstract Details

2013, Master of Science in Polymer Engineering, University of Akron, Polymer Engineering.
Several Railroad Ties manufactured by Steel Dynamics which use steel and concrete as core and recycled rubber and plastic (polyethylene/polypropylene blend) composite material as insulation shell have been studied. The company reported that there were some cracks on the surface of the tie. This work was performed to determine the cause of these cracks. For this purpose, we executed an experimental and analytical program which included residual stress analysis, tensile and hardness tests, thermal expansion test, differential scanning calorimetry (DSC), and thermal gravimetric analysis (TGA).The presence of recycled crosslinked polyethylene, immiscible with the rest of the blend constituents is thought to be the main reason of cracks.
