[I-422] CFRP鋼接合部に使用されるエポキシ接着剤の吸水効果に関する基礎的研究
キーワード：エポキシ接着剤、水分拡散、環境の悪化、CFRP-スチールジョイント
Recent years, CFRP was usually used to reinforce steel structures. One major drawback when it comes to
using CFRP composites for strengthening and repairing steel structures is the lack of knowledge relating to the long-term performance and durability properties of CFRP/steel bonded joints. Particularly, adhesive degradation is the most widely concerned problem. In this study, the moisture test was used to the influence of the environment on the water absorption rate. The DSC test and FTIR test were used to investigate the effect of water on the internal structure after the resin absorbed water.
