Abstract

Carbon fiber-reinforced polymer (CFRP) is widely used in transportation and aerospace. However, CFRP is susceptible to impact damage, leading to defects such as cracks and delamination. Moreover, detecting 4-J low-energy impact damage in CFRP is challenging. To address this issue, this article uses eddy current pulsed thermography (ECPT) in combination with the optical flow amplitude-based method (OFABM) for nondestructive testing. The optical flow is used to track the transient heat propagation state of the CFRP composites, and the principal component analysis (PCA) is employed to extract defect information from the optical flow amplitude. A relationship between optical flow amplitude and impact energy is established, allowing quantitative evaluation of impact damage. The experimental results demonstrate that the OFABM effectively detects 4-J low-energy impact damage in CFRP and has the potential for the quantitative assessment of impact damage.

基于光流振幅的 CFRP 冲击损伤检测和定量评估方法

碳纤维增强聚合物（CFRP）广泛应用于交通运输和航空航天领域。然而，CFRP 容易受到冲击损伤，导致裂缝和分层等缺陷。此外，检测 CFRP 中的 4-J 低能量冲击损伤也具有挑战性。为解决这一问题，本文将涡流脉冲热成像（ECPT）与基于光流振幅的方法（OFABM）相结合，用于无损检测。光流用于跟踪 CFRP 复合材料的瞬态热传播状态，并采用主成分分析法（PCA）从光流振幅中提取缺陷信息。建立了光流振幅与冲击能量之间的关系，可对冲击损伤进行定量评估。实验结果表明，OFABM 能有效检测 CFRP 中的 4-J 低能量冲击损伤，具有定量评估冲击损伤的潜力。
