A Study on the Strain Measurement of Laminated Composite Structures Using Fiber Bragg Grating Sensors

In order to be used for the primary structures, composite structures must ensure structural reliability and durability. It is therfore desirable to carry out real-time health monitoring of composite structures as loading history. In the present study, fiber Bragg grating(FBG) sensors which have the advantage of multiplexing based on wavelength division multiplexing(WDM) technology were used for the sensing part of the smart composite structures....
