Abstract
We perform coarse-grained molecular dynamics simulations of epoxies to study the way their microstructure depends on how they are processed. We then perform additional simulations to calculate the glass transition temperatures of our systems and compare against similar experimental systems. We find that the glass transition temperatures of our un-toughened epoxy systems match up well with experiments. This work enables the structure of experimentally-relevant volumes of epoxies to be predicted, a problem that is intractable for many more detailed representations of epoxies.
