Minimizing The Dimensional Change In Two Component Epoxy Based Thermoset Adhesives Through Adapting Mix Ratio And Initial Crosslink Density, Jefferson Peter Norman

Materials Engineering

Meissner Filtration uses amine-hardened epoxy as a high-performance adhesive to encapsulate hollow fiber membranes at the ends of rigid filter housings. Dimensional change of the epoxy while curing can result in residual stress formation that is detrimental to the manufacturing of the filter and causes structural integrity issues when the filter is used in industrial processes where heating and cooling cycles are implemented. The residual stresses can cause cracks, microscopic fractures, and delamination from the housing, resulting in failure of the filter. The goal of this project was to evaluate how changes in processing conditions could minimize dimensional variability due …
