Research on the Static Load Response of FsFBG Embedded in Carbon Fiber Composite Laminates

In this paper, the fsFBG sensor was embedded in the carbon fiber composite laminate, and the static load experiment was carried out on the carbon fiber composite laminate, and the response characteristics of the fsFBG sensor under different loading distances and different loading angles were analyzed. Experiments show that the fsFBG sensor can monitor the load change well, and the absolute value of the central wavelength variation decreases linearly with the increase of the distance of the loading point, and increases linearly with the increase of the angle between the loading point and the axial direction of the grating.
