摘　　要：复合材料承压结构是指采用复合材料制造的用于承受压力的部件,例如车载储氢容器、液氧贮箱、固体火箭发动机等.结构具有轻质高强、可设计性好等诸多优点,在航空航天、汽车和石化等领域得到广泛应用.然而在严苛服役条件下,复合材料承压结构的损伤积累及扩展极易导致部件失效,因此为提高其在役安全性,发展先进结构健康监测技术至关重要.本文首先详细对比了超声导波、声发射、红外、光纤光栅等监测方法的优缺点,重点阐述了复合材料承压结构健康监测方法及研究进展.其次,针对复合材料承压结构的材料特征,讨论了植入式微纳材料传感器在纤维/基体界面和层间性能监测方面应用及面临的关键挑战.最后,探讨了新型传感技术及人工智能方法的研发进展,并分析了其在复合材料承压结构在役安全保障领域的应用前景.Composite pressure structures refer to components made of composite materials designed to withstand pressure,such as hydrogen storage tanks for vehicles,liquid oxygen tanks,and solid rocket engines.These structures possess numerous advantages including lightweight,high strength,and excellent design flexibility,making them widely employed in aerospace,automotive,and petrochemical industries.However,under severe service conditions,the accumulation and propagation of damage in composite pressure structures can easily lead to component failure.Therefore,the development of advanced structural health monitoring technologies is crucial for enhancing their in-service safety.This paper begins by comprehensively comparing the advantages and disadvantages of monitoring methods such as ultrasonic guided waves,acoustic emission,infrared,and fiber optic gratings,focusing particularly on the methods and research progress of structural health monitoring for composite pressure structures.Subsequently,addressing the material characteristics of composite pressure structures,we discuss the application and key challenges of implanted micro/nano-material sensors in monitoring the interfacial and interlaminar properties of fiber/matrix.Finally,we explore the development progress of novel sensing technologies and artificial intelligence methods,and analyze their application prospects in the in-service safety of composite pressure structures.
