碳纤维增强复合材料在航空环境中的应用领域越来越广泛，并将在适当的时候扩展到汽车和休闲领域。这些材料需要以合理的成本和丰富的经验进行鉴定，超声波检测迄今为止已成为无损检测 (NDT) 的首选程序。然而，复合材料的两相各向异性结构意味着各种挑战，例如散射、光束偏斜和声场失真，使缺陷的定位、尺寸确定和表征变得复杂。除了制造阶段的资格认证之外，一旦复合材料老化（可能是由于机械疲劳、化学老化或辐射），就会出现额外的任务。同样，基于超声波的材料表征将允许在材料的生命周期中进行比较。生成的知识可用于现场监测程序，例如在结构健康监测（SHM）的背景下考虑。
Carbon fibre reinforced composite materials enjoy an increasing field of application in the aeronautical environment and are due to expand into the automotive and leisure sectors in due course. Those materials need to be qualified at reasonable cost and with considerable experience, where ultrasonic testing has become the procedure of primary choice for nondestructive testing (NDT) so far. However, the two-phase anisotropic structure of a composite material implies a variety of challenges such as scattering, beam skewing, and sound field distortion complicating the localization, sizing, and characterization of defects. Besides qualification during the manufacturing stage, additional tasks emerge once the composite material ages, maybe by mechanical fatigue, chemical ageing, or irradiation. Again characterisation of the material based on ultrasonics would allow comparisons to be made along a material’s life cycle. The knowledge generated could be used for in-situ monitoring procedures such as considered in the context of structural health monitoring (SHM).
