摘　　要：环氧树脂是一类具有优异性能的热固性材料,广泛应用于航空航天、车辆工程等领域,但由于其交联结构,环氧树脂韧性较差。其中纳米粒子改性环氧树脂在增韧环氧树脂的同时,其力学性能也有所提升。对三种纳米粒子改性环氧树脂的研究进展进行了综述,包括纳米二氧化硅、石墨烯及衍生物和碳纳米管,对改性效果进行了详细的阐述分析,讨论了增韧机理。The epoxy resin is a type of thermosetting material with excellent properties.It is widely used in the aerospace,vehicle engineering and other fields,but due to its crosslinked structure,the epoxy resin is relatively brittle.The nanoparticle toughens the epoxy resin while improves its mechanical properties.The research progress in three kinds nanoparticle modifying epoxy resins are summarized,including the nano-silica,the graphene and its derivatives and the carbon nanotubes.The modification effect is analyzed in detail,and the toughening mechanism is discussed.
