On December 10, 2021, the home-made carbon fiber stayed cable hanging ceremony of the Xinghua Road Crossing Haihe Bridge Project was held in Liaocheng, Shandong. This marked the first time that domestic carbon fiber was used in the main cable of the bridge. The carbon fiber stay cables for this project were provided by LiuGong Ouweimu.

The Tuhai River Bridge on Xinghua Road in Liaocheng is the first vehicle bridge in China to use carbon fiber cable stays. Academician Yue Qingrui of the Chinese Academy of Engineering said that the carbon fiber stay cable used this time fills the gap in the domestic vehicle bridge industry and is the largest span currently in the world. The proportion of carbon materials is only 1/5 of that of steel, and the strength is higher than that of steel cables. 1/4.

Significant

The application of carbon fiber stay cables is a solid step for China to apply carbon fiber cables in larger-span bridges in the future, and is a milestone in the field of civil engineering in China and the world.

As a national strategic high-performance fiber composite material, carbon fiber was mainly used in aerospace in the past. In recent years, the material has gradually been applied to civil engineering and building structures. The application of carbon fiber can extend the service life of engineering structures, reduce operation and maintenance costs, and significantly reduce energy consumption and carbon emissions during the entire life cycle of engineering structures.

Innovation is the primary driving force for the development of the enterprise. While improving its own innovation capabilities, LiuGong Ouweimu continuously increases R&D investment, strives to build a first-class R&D platform, and develops a comprehensive strategy with well-known research institutes and design institutes in and outside the region Cooperation to jointly break through the core technical problems of the prestressing industry, quickly transform scientific and technological achievements into productivity, and drive high-quality development with innovation.
