Strain Monitoring of T-Stiffened Panels Subjected to Low-Velocity Impact Using Embedded FBG Sensors

Abstract:

The strain at the low-velocity impact proceeding was monitored by the fiber Bragg grating (FBG) sensors embedded in the triangle area of the T-stiffened panels. The results show that the strain in whole impact process can be monitored by FBG sensors. Furthermore, the max-strain measured by FBG sensors changed sensitively depending on the different impact energy. It can be hoped that the FBG sensors can be used as online-monitoring technique to improving the safety of the composite structures.
