摘要：

In this paper, carbon fiber reinforced plastic (CFRP) laminates (pristine and delaminated) are addressed for the purpose of damage assessment. Recently developed Doppler effect-based fiber optic (FOD) sensor was bonded on surface of each CFRP laminate to acquire piezoceramic-disc-excited guided waves propagating in the specimen. Characteristics of the captured guided wave signals were extracted by taking advantage of two well-developed signal processing algorithms, namely, linear-phase finite impulse response filter and Hilbert transform, so as to investigate the influence of the delaminations to the guided wave propagation. When guided waves are incident on discontinuities, mode conversion may occur as a result of satisfying the boundary conditions along the discontinuities. Both the dispersive characteristics of multi-mode guided waves and features of the guided-wave-generated fundamental shear horizontal (SH0) wave were applied for damage evaluation and multiple-damage detection. The results demonstrate that the FOD sensor is effective in multiple delamination detection for CFRP laminates because of its omnidirectional property in ultrasonic detection.
