China’s Changtai Yangtze river bridge to use the world’s largest carbon fibre composite cables

In China’s Jiangsu province, the Changtai Yangtze river bridge claims to be the world’s largest-span road-rail dual-purpose cable-stayed bridge currently under construction. With a total length of 10.03 kilometers, it is connecting the tow cities of Changzhou and Taizhou across the Yangtze river.

The biggest highlight of this bridge is the use of the world’s largest carbon fibre composite cables. Carbon fibre cables have excellent properties such as light weight, high strength, corrosion resistance, fatigue resistance, low relaxation rate and low linear expansion coefficient. The cables make full use of the tensile strength properties of carbon fibre and achieve a high-performance bridge structure with lightweight and long life characteristics.

In recent years, carbon fibre cables have been used in the Tuhai river bridge in Shandong Province and in another bridge in Jiangsu Province. The successful application of carbon fibre cables on bridges is a milestone in the field of civil engineering, opening up new ideas for bridge design.
