摘要：
With the rapid development of marine engineering in China, the degradation and destruction of reinforced concrete structures due to the steel corrosion in the marine environment are more and more prominent. Based on the properties of light weight, high strength, and excellent resistance to corrosion, the composite structure of fiber reinforced polymer (ＦＲＰ) and concrete is considered as a kind of superior materials for marine structure. This paper mainly introduces the deterioration mechanism of ＦＲＰ in the marine environments including water and alkaline solution immersion, ultraviolet radiation. The mechanical properties of ＦＲＰ including tensile, bending, shear, and compression strength are introduced. Besides, the deterioration of ＦＲＰ⁃concrete interface and its effects on the performance of ＦＲＰ reinforced concrete structures are reviewed. The interfacial bonding strength and mechanical properties of the composite structure of ＦＲＰ and concrete in marine environment are emphatically discussed, which can lay a theoretical foundation and provide a research guide for further study and application of composite materials and structure in the marine environment. © 2023 Cailiao Daobaoshe/ Materials Review.
