摘　　要：探索利用碳纳米管(CNTs)对炭纤维增强复合材料的界面进行增强而影响的力学行为是研究碳纳米管增强纤维复合材料(CNTs/CFRP)的重要一环。传统的界面增强是将CNTs直接分散在基体中,并不能有效地利用CNTs的机械与热力学性能以及电学性能。因此,在界面处利用碳纳米管进行增强是一种相对完全利用CNTs各种性质的有效手段。综述了在界面处利用CNTs增强的炭纤维复合材料的以拉伸性能、断裂韧性为主的力学性能、以热导率为主的热力学性能以及以电导率为主的电学性能。最后,对CNTs的应用和产业化提供展望和建议。It is an important part of the study of carbon nanotube reinforced fiber composites to explore the mechanical behavior of carbon nanotube reinforced fiber composites(CNTs/CFRP).Traditional interfacial strengthening, in which CNTs are directly dispersed in the matrix, does not effectively utilize the mechanical, thermodynamic and electrical properties of CNTs.Therefore, enhancement with carbon nanotubes at the interface is an effective means to make full use of various properties of CNTs.The mechanical properties, mainly tensile and fracture toughness, and thermodynamic properties, mainly thermal conductivity and electrical properties of carbon fiber composites reinforced by CNTs at the interface were reviewed.Finally, the prospects and suggestions for the application and industrialization of CNTs are provided.
