Presentation Title or Topic Comparative Analysis of Water-induced Response in 3D-Printed SCF/ABS Composites under Controlled Diffusion
Presenters Md Tareq Hassan

Prior to commencing full-scale production and installation of underground wireless power transmission (WPT) systems, it is imperative to conduct comprehensive investigations to ensure their protection against environmental threats (i.e., elevated temperature, water/moisture ingression, soil corrosion, etc.). Applying epoxy protective coating on the WPT system can be a solution. But, epoxy materials are susceptible to environmental aging, resulting from long-term damage from water/moisture and swelling. This study aims to determine the structural performance of epoxy protective coating before and after water diffusion at various temperatures. A series of water diffusion tests was conducted at room (23°C) and elevated (50°C) temperatures to assess the temperature-dependent diffusion characteristics of two commercially available electronics casting and encapsulation epoxy materials (MG Chemicals 832TC and 832FX). Low-velocity impact (LVI) tests were performed on pristine epoxy specimens and those subjected to water diffusion. A finite element analysis (FEA) framework was developed by coupling heat transfer, mass diffusion, swelling and LVI analyses to investigate water-induced damage characteristics and followed by LVI resistance of the epoxy coating. The numerical results exhibited a high degree of consistency with the experimental findings indicating that it can be used as a baseline for predicting epoxy coating performance on WPT systems under harsh water environments.
