Abstract: The epoxy resin/polyether amine thermosetting system was modified with amineterminated liquid ATBN as a impact modified, and their gel time, morphology and mechanical properties were investigated. The results indicated that this thermosetting system obtained a significant toughening effect when 15 phr of ATBN was added. Compared to pristine epoxy resin, the impact modified thermosetting system achieved an improvement in impacted strength by 65 %, in bending strength by 14 % and in tensile shear strength by 73 %.
