Abstract: The research on advanced anticorrosion materials and technologies has always been a hot spot. This paper summarizes the application status of domestic non-metallic materials for aids to navigation (ATON) technology in marine environment, analyzes the cost and performance differences of each material for aids to navigation. The results show that reinforced concrete light beacons shall be gradually sifted out. Steel and FRP (Fiber Reinforced Plastic)-polyurea composites material and UHMWPE (Ultra High Molecular Wight Polyethylene) ATONs are still the main structural forms of light beacons. Steel buoys are still the main structural form of buoys by now. The application of UHMWPE buoys is gradually expanding, and the application scale of FRP buoys is shrinking. Finally this paper puts forward the development trend of non-metallic materials for aids to navigation. The future development trend of ATONs is: improving the performance of non-metallic materials, optimizing the structure design of non-metallic material ATONs, increasing the research and development investment of non-metallic material ATONs, especially non-metallic material ATONs with light weight, high impact resistance property, low cost, anticorrosion, anti bio-foul and low water absorption rate, and formulating relevant technical specifications and standards in time.
