Influence of cure conditions on glass transition temperature and density of an epoxy resin

摘要

AbstractThe glass transition temperatureTgand density of a TGDDM‐DDS epoxy resin system were studied as a function of cure times at various cure temperatures. BothTgand density asymptotically increased toward a maximum value with increasing cure time. TheTgand density measurements were related to the extent of cure, and the relationship in both cases was found to be independent of cure temperatur
