摘要 The excellent physical properties of epoxy resin are not available in other thermoplastic materials, but the toughness of pure species samples is relatively poor. In this experiment, epoxy resin was toughened by adding carboxylated-terminated liquid acrylonitrile rubber and cerium oxide nanoparticles. The samples were subjected to performance tests, including impact tests, scanning electron microscopy, Energy Dispersive Spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and Thermal stability analysis. Based on the analysis of the performance test results, the best toughening mass ratio of the raw material of the double toughened epoxy resin was obtained. The mass ratio of epoxy resin to double toughening agent was 4 : 1. In the double toughening agent, the mass ratio of carboxylated-terminated liquid acrylonitrile rubber to cerium oxide nano was 4 : 1. The impact strength of the double toughened epoxy resin at the optimum toughened mass ratio can reach 31.77 KJ/m(2). This is an impact strength increase of 692 % compared with the pure epoxy resin.
