The fiber Bragg grating (FBG) sensors were used to measure the strain of the composite laminate plate under low velocity impulse in this work.The resistance strain gauges and the FBGs were bonded on the composite laminate plate symmetrically,while the impact load was applied to the centre of the composite laminate plate and the impact loads with 8 different levels (from small to big) were supplied. The experiment results showed that the measured data obtained by FBG sensors were consistent with that of the resistance strain gauges bonded symmetrically. This indicated that FBG could be used the impact strain measurement of composite laminate plate.The impact damaged location of the composite laminate plate has been identified successfully by combining the peak responses of the impact load from 5 FBF sensors with the proposed peak response enveloping surface method. New damage location identification method and damage index from Fiber Bragg Grating sensors was proposed to monitor impact damage of composite laminate plate.
