纤维增强聚合物(Fiber Reinforced Polymer/Plastic,简称FRP)一般具有不透水和不透气的性质,是一种阻锈性能良好的材料.本文介绍了FRP加固锈蚀混凝土结构抗腐蚀特性的最新研究成果,分析了FRP种类、FRP树脂胶、FRP层数和纤维方向等对防腐效果的影响,并探讨了FRP加固锈蚀混凝土结构的防腐阻锈机理.

Fiber reinforced polymer/plastic (FRP) can resist corroding because they are relatively watertight and airtight. This article will report some research on resistance to corrosion of reinforced concrete structure retrofit-ted with FRP. The influencing factors of the anticorrosion performances of reinforced concrete structure retrofitted with FRP: the type of FRP, the type of epoxy, the number of wraps layers, and the fabric orientation are ana-lyzed. The antieorrosion mechanism of reinforced concrete structure retrofitted with FRP is discussed.
