Abstract
Need is for diversified material tests and member tests of CFRP tendons to develop NSM (Near Surface Mounted) strengthening using CFRP. To that goal, research should be preliminary conducted on the bond characteristics between the CFRP tendon and the filler. Accordingly, this study performed bond test on ϕ5 mm CFRP tendons of which surface were treated by grinding or coated with sand coating, screwed-sand coating, and aluminum-oxide coating to improve the bond characteristics. The experimental results showed that the surface treatment of the tendon increases the bond strength by about 3 times on the average compared to the non-coated tendon and, that there is practically no difference in the bond strength according to the type of coating. The reason for such result could be verified through the failure mode of the specimens. That is, the bond strength between the CFRP tendon and the resin used to fix the sand coating and oxide coating appeared to be smaller than the bond strength between the surface treatment and the filler. Therefore, surface treatment shall be imperatively executed for the CFRP tendon to improve its bond performance. Further research should focus on the improvement of the bond performance between the CFRP tendon and the resin to achieve that purpose.
