In order to improve the cracking resistance of the encapsulating insulating material for dry-type air-core reactor, it is necessary to improve the toughness of the epoxy resin composite while ensuring the good electrical properties. In this paper, an epoxy glass fiber composite with good mechanical and electrical properties was obtained by adding different content of epoxy-terminated liquid nitrile butadiene rubber (ETBN), different content and partical size of Al2O3 powders to the epoxy glass fiber (EP/GF) composite, and its structure and morphology, mechanical and electrical properties were tested. The results show that when the mass fraction of ETBN, 5 μm Al2O3, and 100 nm Al2O3 is 10%, 30%, and 3%, respectively, the bending strength of the EP/GF composite reaches the highest of 291.0 MPa, which increases by 33.5% than that of the unmodified composite, and the electric strength is 24.3 kV/mm, the comprehensive properties are the best.
