使用频率为15-20 kHz的基本反对称A（0）Lamb模式，证明了用于复合材料在役健康监测的成本和时间有效的检测策略。原则上，该方法涉及分析压电装置与试件边界或不连续性（缺陷）相互作用后产生的透射和/或反射波。在目前的工作中，该技术的适用性，检查夹层和修复复合材料层压碳纤维增强结构进行了探讨。(c)2005爱思唯尔有限公司保留所有权利。
A cost and time effective inspection strategy for in-service health monitoring of composites is demonstrated using the fundamental anti-symmetric A(0) Lamb mode at frequencies of 15-20 kHz. In principle, this method involves analysis of the transmitted and/or reflected wave generated by a piezoelectric device after interacting with the test-piece boundaries or discontinuities (defects). In the present work, the applicability of the technique to inspect sandwich and repaired composite laminated carbon fibre reinforced structures is explored. (c) 2005 Elsevier Ltd. All rights reserved.
