Two rectangular plates, assimilable to beams, one with embedded fiber optic sensors and one with the sensor glued on its surface have been manufactured using a prepreg carbon fiber fabric. The sensors, specifically two Fiber Bragg Gratings (FBGs), have been embedded in the same in-plane position but at different depths so as to be in opposite position with respect to the neutral axis. A second plate with lower natural frequency has been tested to prove the feasibility of a modal analysis by the use of a fiber Bragg Grating. Correlation between excitation and response will be verified to check from a macroscopic point of view the good bonding between fiber and Carbon Fiber Reinforced Plastic (CFRP) composite.

Abstract
Two rectangular plates, assimilable to beams, one with embedded fiber optic sensors and one with the sensor glued on its surface have been manufactured using a prepreg carbon fiber fabric. The sensors, specifically two Fiber Bragg Gratings (FBGs), have been embedded in the same in-plane position but at different depths so as to be in opposite position with respect to the neutral axis. A second plate with lower natural frequency has been tested to prove the feasibility of a modal analysis by the use of a fiber Bragg Grating. Correlation between excitation and response will be verified to check from a macroscopic point of view the good bonding between fiber and Carbon Fiber Reinforced Plastic (CFRP) composite.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
