Development and sensing performance study of a smart CFRP cable assembled by multi-group anchorage units

Carbon fiber reinforced polymer (CFRP) can be applied for bridge cables due to its excellent properties. As the important load-bearing structural component, real-time force monitoring of CFRP cable is required. This paper presents a new smart that combines self-sensing rods with embedded sensors and anchorage system using extrusion technology. By embedding optical (OF) coaxial Fabry-Perot interferometer (CCFPI) into respectively, two types (CFRP-OF rod CFRP-CCFPI rod) were fabricated. A unit an process was proposed as basic component cables. Anchorage units holding CFRP-OF tested obtain their sensing mechanical Three assembled form functionality. verification test carried out confirm capability force. The results demonstrate composed multiple has good potential in engineering.
