High tensile strength and stiffness as well as high fatigue life, low weight and excellent chemical resistance are material properties of carbon fibre composites (CFRP) which make these materials interesting for stay cable systems. The key problem to which the application of stay cables as well as tendons is faced is the anchoring. This paper describes the properties of CFRP-wires, the requirements to stay cables or tendons and the development of such a system through calculations and experiments along with a successful field stress test of a CFRP based stay cable.
