Their use is particularly advantageous in infrastructure exposed to aggressive environments, such as chloride-induced corrosion, where improved durability and reduced maintenance are critically required. In this study, a 10 mm diameter round-bar-type CFRP cable was developed using a pultrusion process, and its applicability to structural systems was comprehensively evaluated through material testing and field implementation. Mechanical performance was assessed through tensile, relaxation, and fatigue tests. The developed CFRP cable exhibited an average tensile strength of 3019 MPa and an elastic modulus of 176.9 GPa, demonstrating mechanical properties comparable to or better than those of conventional prestressing tendons. The final relaxation ratio was measured as 2.25%, satisfying the low-relaxation criterion specified in KS D 7002. In the fatigue test, the cable sustained 2,000,000 loading cycles under a stress range corresponding to 60\u201366% of the ultimate tensile strength without fracture or significant stiffness degradation, confirming its excellent fatigue durability. In addition, the developed CFRP cable was implemented in a cable-net structure to verify its constructability and structural applicability in practice. The field application confirmed that the lightweight CFRP cable enabled convenient transportation and installation, while stable prestress introduction was achieved using the same tensioning procedure as that for conventional steel cable systems. The results demonstrate the integrated feasibility of the developed CFRP cable in terms of both material performance and practical structural application. This study provides experimental evidence supporting the structural use of CFRP tendons and offers a technical basis for the future development of design provisions and broader infrastructure applications.<\/jats:p>","DOI":"10.3390\/polym18070811","type":"journal-article","created":{"date-parts":[[2026,3,27]],"date-time":"2026-03-27T15:45:42Z","timestamp":1774626342000},"page":"811","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Performance Assessment and Field Deployment of Carbon-Fiber-Reinforced Polymer (CFRP) Cables for Infrastructure Applications"],"prefix":"10.3390","volume":"18","author":[{"given":"Sung-Jin","family":"Lee","sequence":"first","affiliation":[{"name":"Korea Institute of Civil Engineering and Building Technology, Goyang-si 10223, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jongeok","family":"Lee","sequence":"additional","affiliation":[{"name":"Korea Institute of Civil Engineering and Building Technology, Goyang-si 10223, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Woo-Tai","family":"Jung","sequence":"additional","affiliation":[{"name":"Korea Institute of Civil Engineering and Building Technology, Goyang-si 10223, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1179\/095066001101528420","article-title":"Concrete deterioration: Causes, diagnosis, and minimising risk","volume":"46","author":"Hobbs","year":"2001","journal-title":"Int.
