摘要
概述了FRP加固混凝土结构耐久性方面的研究成果,介绍了玻璃纤维、碳纤维和芳纶纤维3种复合材料加固混凝土结构在化学腐蚀、干湿循环和冻融循环条件下力学性能的变化情况和破坏机理,对如何提高纤维增强塑料加固混凝土结构耐久性及今后研究方向提出了几点建议和看法.
This article discoursed on the fruit of research on durability of the fiber-reinforced plastic (FRP) strengthened concrete structures, then introduced the mechanical properties and failure mechanisms of concrete structures reinforced with glass FRP (GFRP), carbon FRP (CFRP) and aramid FRP (AFRP) under different experimental conditions (chemical eroding, wet/dry cycle and freeze-thaw cycle). Finally some suggestions were put forward about research direction for enhancing durability of FRP reinforced concrete structures
