提出了一种基于表面贴装光纤光栅（FBG）传感器的复合材料分层检测方法。在该方法中，测量静态应变以准确地检测分层区域。实验结果表明，光纤光栅中心到分层区的距离与波长漂移量之间存在一定的关系。并对该方法的灵敏度进行了讨论。结果表明，该技术的结构健康监测应用的可行性。
A method to detect delamination in a composite material, using a surface mounted fiber Bragg grating (FBG) sensor, is proposed in this paper. In this method, the static strain is measured to accurately detect the delamination area. Experiments are carried out and results show the relation between the wavelength shift and the distance between the FBG center and the delaminated area. The sensitivity of this method is also discussed. Results show the feasibility of this technique for structural health monitoring applications.
