在本文中，碳纤维增强塑料（CFRP）层合板的多损伤评估的目的。基于多普勒效应的光纤（FOD）传感器被用来捕捉导波在CFRP层压板中传播。利用线性相位有限脉冲响应滤波器和希尔伯特变换提取了导波信号中的基本对称（S0）和反对称（A0）兰姆波特征，系统研究了分层对导波传播的影响。将多模态Lamb波的频散特性和Lamb波激发的基本剪切水平（SH0）导波特性用于损伤评估和多损伤识别。结果表明，FOD传感器是有效的复合材料层合板的多损伤识别，因为它是全方位的超声检测。
In this paper, carbon fiber-reinforced plastic (CFRP) laminates are addressed for the purpose of multiple damage assessment. Doppler-effect-based fiber-optic (FOD) sensors were used to capture guided waves propagating in the CFRP laminates. Characteristics of the fundamental symmetric (S0) and anti-symmetric (A0) Lamb waves in captured guided-wave signals were extracted by taking advantage of linear-phase finite impulse response filter and Hilbert transform, so as to systematically investigate the influence of delaminations on guided-wave propagation. Both dispersive characteristics of multi-mode Lamb waves and features of the Lamb wave-excited fundamental shear horizontal (SH0) guided wave were applied for damage evaluation and multiple damage identification. Results demonstrate that the FOD sensor is effective in multiple damage identification for composite laminates because it is omnidirectional in ultrasonic detection.
