| In order to confirm the durability of FRP composites in marine environments, the authors have carried out the exposure tests for 6 types of FRP cables (re-bars) including CFRP, AFRP and GFRP under severe marine environment in Japan for up to 17 years. Table 1 shows the type of cables used in this study and Figure 1 show the exposure conditions. The exposure environments during the tests have a variety of conditions such as with/without direct sunshine or tension.Figure 2 shows the results of residual strength of CFRP specimens. The result suggests that tested CFRP have a good durability in marine environment. AFRP also showed similar results, however the results suggest the requirement of careful confirmation on durability for GFRP and VFRP. The authors also show the results of creep performance and chemical analysis in the report. |
