摘要：

The FBG sensors, embedded in triangle region of composite T-stiffened panels, were used to monitor the strain change during curing process and quasi-static compression real-timely. The results show that the compression load of stiffened panels with the FBG sensor embedded along the stiffener is the same as that without the FBG sensor. The FBG sensor embedded in the triangular area of the stiffened panels can effectively monitor during the curing process, and it can also be used to monitor the temperature and strain changes real-timely after curing process. In the quasi-static compression process, the strain curve measured by the FBG sensor is the same as the force-displacement curve. The FBG sensors can monitor accurately the damage such as lamination and cracking in the stiffened panels without affecting the property of the stiffened panels.
