THE INFLUENCE OF INFUSED RESIN ON DURABILITY OF CFRP SHEETS UNDER THE ENVIRONMENT OF NORTHWEST CHINA
-
摘要: CFRP加固广泛应用于土木工程,对耐久性能的研究已得到了工程界的重视。通过对目前土木工程加固常用的两种CFRP及其配套树脂在西北地区自然环境条件下耐久性进行初步的对比试验研究。试验每组试件设为5件,进行了16组共80个试件的试验。通过2年初步试验,结果表明,碳纤维片材耐久性与浸润树脂耐久性有一定的相关性。Abstract: CFRP sheets strengthening is widely used in civil projects and much attentions is paid to their durability. Durability of two common CFRP sheets and resin were compared and studied under the nature environment of northwest China. Each group has 5 pieces of sheets and sixteen groups of sheets which are 80 sheets were tested in recent 2 years. The results indicate that durability of CFRP sheets has some relationship with durability of infused resin.
