摘要:
借助光纤布拉格光栅(FBG)传感器,在不同浸润时间下,对碳纤维复合材料(CFRP)锚固结构进行周期荷载实验,探究水浸与周期荷载下CFRP锚固结构的耐久性.试验结果表明:随着循环次数的增加,环氧体塑性变形减小,并趋于稳定;水浸与周期荷载作用下,锚具内CFRP筋发生变形,但无脱锚现象发生;CFRP筋与环氧体界面受水浸环境影响小,筋材表面无腐蚀.
Abstract:
With the help of fiber Bragg grating(FBG)sensor, periodic loading experiments were carried out on carbon fiber reinforced polymer(CFRP)anchorage structure under different wetting time to explore the durability of CFRP anchorage structure under water immersion and periodic load. The experimental results show that with the increase of cycle times, the plastic deformation of epoxy body decreases and tends to be stable; CFRP bars deform in anchorage, but no slip occurs under water immersion and periodic load; the interface between CFRP bars and epoxy body is less affected by the water immersion environment, and there is no corrosion on the surface of CFRP bars.
