- Abstract:
- In this paper, ABAQUS was used to simulate the response of carbon fiber composite laminates under low velocity impact. It was found that the increase od the impact energy, the maximum stress of each layer incread. By using the characteristic that the center wavelengths of FBG sensors to monitor the response of low velocity impact. By analyzing the center wavelength captured by optic fiber grating demodulator, the relationship between the impact energy and the peak wavelength shift of sensors was found. Experimental results showed that, the embedded FBG sensors were able to accurately capture the transient impact signal and the peak wavelength shift of sensors could determine the size of the impact energy. With the increase of the impact energy, the peak wavelenght shift increase as well as the maximum stress of layer.
