Device for testing durability of FRP force transmission rod and test method

The invention discloses a device for testing the durability of an FRP force transmission rod and a test method. The device includes a PVC pipe sleeve, a hydraulic lock, and a silica gel sealing strip.According to the test method of the invention, an FRP force transmission rod is inserted into the PVC pipe sleeve of the device; the PVC pipe sleeve is filled with a corrosion solution, so that a corrosive environment can be simulated; constant-temperature maintenance is carried out; the changes of the mass, interlayer shear strength, bending strength and bending elastic modulus of the FRP forcetransmission rod before and after the maintenance are measured; and the durability of the FRP force transmission rod is judged. According to the device and the test method of the invention, the destruction process of the FRP force transmission rod is observed from a micro perspective, and the exploration of the corrosion mechanism of the FRP force transmission rod can be benefitted, the long-termcorrosion state of the FRP
