Embodiment Construction
[0038] The present invention will be described below in conjunction with specific embodiments.
[0039] Such as figure 1 and figure 2 As shown, a self-monitoring DOFS-FRP cloth includes FRP cloth 1 and a distributed optical fiber sensor 2 (referred to as DOFS) in the shape of a long cable and continuously extending. The distributed optical fiber sensor 2 includes a built-in bare optical fiber 21. An outer protective sheath 22 wrapped around the periphery of the built-in bare optical fiber 21 and extending along the length direction of the built-in bare fiber 21 .
[0040]Among them, the FRP cloth 1 is formed by weaving fibers through a loom. During the process of weaving and forming the FPR cloth through the loom, the fibers that make up the FRP cloth 1 are fed into the loom together with the distributed optical fiber sensor 2, and the distributed optical fiber sensor 2 is weaved and embedded in the FRP cloth 1, and the distributed optical fiber sensor 2 and the FRP cloth 1...
