摘要：
Cyanate ester resin (CE) is a high-performance resin widely used in aerospace, but its disadvantages such as high curing temperature and poor toughness affect its application fields. In this paper, CE was modified with hyperbranched epoxy resin (E102), and the effects of E102 on the curing behavior, thermal and mechanical properties of CE system were systematically studied. The results show that E102 can significantly promote the curing of CE, reduce the curing peak temperature by 16.3 ℃, significantly strengthen and toughen the CE resin, increase the impact strength and bending strength of CE resin by 42.27% and 16.95% respectively, and maintain the heat resistance and high glass transition temperature (282.4 ℃ ). The strong interfacial interaction and good compatibility between resins were confirmed by dynamic thermomechanical analysis (DMA) and scanning electron microscope (SEM), and the mechanism of homogeneous reinforcement and toughening was expounded. The results have important guiding significance for reducing the curing temperature of CE and preparing high toughness CE resin and its composites, which is conducive to its wide application in the field of high and new technology. © 2022, Editorial Board of Polymer Materials Science & Engineering.
