China's 1,000-ton Carbon Fiber Cable Stayed Bridge Will be Put into Use Soon ——OVM and China Construction Eighth Engineering Division Made Great Achievements in Joint Innovation

   On September 8th, Shandong Architecture and Civil Engineering Society organized a delegation of academicians from Chinese Academy of Engineering and industry experts in Liaocheng, Shandong Province, to certify the application scheme of 1,000-ton carbon fiber cable jointly researched by OVM and Engineering Research Institute of China Construction Eighth Engineering Division. Finally, the expert review team highly praised and unanimously approved the application scheme of the carbon fiber cable highway cable-stayed bridge, and it was the first time that carbon fiber was used for cable technology of highway cable-stayed bridge in the history of bridge construction in China.

   As a high-performance structural material, carbon fiber was mainly used in aerospace in the past, and it is a national strategic high-performance fiber composite material with light weight and high strength, excellent durability and fatigue resistance. In recent years, it has made great progress in application to civil engineering and building structures. The Project of Xinhua Road across Tuhai River Bridge in Liaocheng, with a total length of is 388 meters, will refresh the large-span record of applying carbon fiber cables in the field of highway bridge in the world, achieve a new breakthrough in the application field of domestic carbon fiber cables, reduce the operation and maintenance costs during the service period of bridge cables, which is a benchmark project in the industry and of great milestone significance.
   In 2012, OVM applied carbon fiber prestressed rock anchor technology in Aizhai Bridge of Hunan Province. This time, carbon fiber cable technology is applied again in the field of highway bridge stay cable, which is of milestone significance in the civil engineering field in China and even in the world. It is a solid step for China to apply carbon fiber cable in larger span bridges in the future.
