Carbon fibre tie rods were used in the Xiamen Xiang’an Airport project undertaken by China Construction Eighth Engineering Group, realizing the first large-scale application of carbon fibre tie rod systems in the field of long-span space structures.

The carbon fibre tie rod is made of Zhongfu Shenying SYT45S-48K large tow carbon fibre as the Zhongfu Carbon Core (ZFCC), achieving high-efficiency conversion of 48K carbon fibre properties during the pultrusion process.

The diameter of a single carbon fibre tie rod exceeded 20 mm for the first time, and the anchoring efficiency exceeded 95%. The tie rod adopts a new high-strength stainless steel anchor independently designed by ZFCC. At the same time, the integrated anti-corrosion of the rod body and anchorage is achieved.

Zhongfu Carbon Core (ZFCC) affiliated to China Composites group, a subsidiary of CNBM group, is a state-level high-tech enterprise specializing in the production of carbon fibre composite core wires, various special conductors and high-end pultruded composite products. ZFCC has been committed to the field of carbon fibre composite material pultrusion technology for more than ten years, and is also widely involved in other fields such as bridges, construction, and wind power energy. For example, the Danjiang Reservoir bridge uses carbon fibre anchors, the Shanghai Petrochemical Logistics channel and the Tsinghua gallery bridge use self-anchored plate cables, the Linquan River bridge uses CFRP stranded cables, and the Suzhou Jiasheng Cafe uses carbon fibre parallel cables. All cables are made by ZFCC, and the supporting anchor structures are also independently designed by ZFCC.
