Abstract
In this study, the curing behaviors and mechanical properties of DGEBA/Phenol novolac hybrid epoxy resin were investigated with respect to the curing accelerator content. The addition of a curing accelerator promotes the reaction between the epoxy resin and curing agent, and accordingly, differences occur in the curing behaviors and mechanical properties of the epoxy resin. The curing behavior of the epoxy resin was analyzed using DSC, and the thermal decomposition properties were confirmed through TGA. The tanδ, flexural, and impact properties were measured and analyzed via morphological observations. Consequently, it was determined that the curing accelerator content has a great influence on the curing behavior of the epoxy resin, such as the cure rate and activation energy, and also affects the mechanical properties of the resin.
