This research investigates the strain transfer characteristics of embedded FBG in pavement structure and materials by using the relevant theoretical models. Results indicate adhesive layer thickness and sheath modulus are the primary factors influencing the strain transfer coefficient. Fiber Bragg Grating Sensors (FBGS) are gaining increasing attention in the field of experimental stress analysis. They are very well suited to the new materials of glass and carbon fiber reinforced composites which are often used for highly stressed constructions, e. in airplanes and wind power. Fiber Bragg grating (FBG) exhibits strong resistance to electromagnetic interference and excellent linear strain response, making it highly promising for structural health monitoring (SHM) in pavement. The samples were made by the direct pressing method from fiberglass prepregs. Strain sensors based on FBGs are becoming an essential part of smart factory. Due to the difference in the physical and mechanical properties between the optical fiber, protective layer, adhesive layer, and the host material, the strains measured by a fiber Bragg grating (FBG) sensor may not be the actual strains of the host material, which impedes the reliable applications. Fiber Bragg Grating Sensors (FBGS) are gaining increasing attention in the field of experimental stress analysis. in airplanes and wind power.

Fiber Bragg gratings are created by "inscribing" or "writing" systematic (periodic or aperiodic) variation of refractive index into the core of a special type of optical fiber using an intense (UV) source such as a UV. Two main processes are used: interference and masking. The method that is preferable depends on the type of grating to be manufactured. Although polymer optic fibers starting gaining research interest in the 2000s, -doped silica fiber is most commonly used. The germanium.
