Summary: This work introduces a novel in-situ interpenetrating network (IPN) structure composed of epoxy resin, vinyl ester resin (VER), and modified octavinyl polyhedral oligomeric silsesquioxane (EPOSS) for toughening epoxy resin. The incorporation of VER forms IPN structures without phase separation, resulting in improved overall strength and plastic deformation capacity. The EPOSS dispersion in the resin matrix triggers plastic shear deformation toughening and the physical entanglement of EPOSS maintains a balance between toughness and mechanical strength. With only 2 wt% of EPOSS, significant improvements in impact toughness, tensile strength, and Young's modulus are achieved.
