Durability of Strengthening Wooden Members Using CFRP Sheets

Abstract:

Article Preview

This research is to discuss the durability of retrofit wooden members using carbon fiber-reinforced polymer (CFRP) composites. In order to assure the durability, wooden member specimens wrapped CFRP sheets which were subjected to two different environments including UV and freeze-thaw cycling were tested on surface hardness, compressive strength and flexural strength tests. After the above environment conditions and tests, the evaluation of the effect and the durability of wooden members wrapped with CFRP sheets can be made. Throughout the test, it finally can compare if the wooden members painted two layer resins before wrapping with CFRP will increase the effect of retrofit. Results show that both UV and freeze–thaw tests didn’t cause CFRP obvious degradation to hardness index, compressive or flexural strength. After environment test, it shows good bonding between wooden members and CFRP. The painting epoxy resin quantity of CFRP composites is a decisive factor in successful application as repaired wooden members.
