Abstract

Abstract

Carbon fiber composite materials （CFRP） have the advantages of light weight， high strength， corrosion resistance， and fatigue resistance. Among them， CFRP rod cables are more advantageous in bridge structures and long-span space structures. The surface treatment process of the CFRP cable anchoring area is the key to affecting the bearing capacity performance of the anchoring system. This article studies the surface treatment process of the CFRP cable base material and compares the improvement effect of the CFRP rod cable anchoring performance under different surface treatment processes. The results show that polishing the surface of CFRP rod cables with 16-grit sandpaper and bonding 26 to 40 mesh quartz sand can improve the load-bearing performance of anchor nodes by 361.1% compared with smooth rod cables. The research results can provide an important basis for the production of improved CFRP rod and cable anchor systems.
