Description
Summary:The curing reaction of the tetra-functional epoxy resin N, N, N', N'-tetraglycidyl-4,4'-di-aminodiphenyl methane (TGDDM) with diaminodiphenyl methane (DDM) and diaminodiphenyl sulfone (DDS) in the presence or absence of fortifier has been studied by differential scanning calorimetry (DSC). The overall activation energy of the curing reaction is in the range of 85–180 kJ mol −1. The thermal degradation studies of cured epoxy resin were carried out by thermogravimetric analysis (TGA). The overall activation energy for the degradation process is observed to be in the range of 53–82 kJ mol −1.
