必须评估聚合物复合材料中由各种冲击引起的损伤,以预测部件的冲击后强度和剩余寿命,特别是当冲击发生在与人类安全相关的结构中时(例如,在飞机中)。X射线断层扫描是研究具有高分辨率的内部结构的常规标准。然而,当撞击区域不能从结构中取出时,它几乎没有用处。此外,X射线断层扫描昂贵且耗时。最近,我们已经证明,kHz速率的激光超声(LU)扫描仪是非常有效的定位大的缺陷和评估的材料结构。在这里,我们表明,在受冲击的碳纤维增强聚合物(CFRP)复合材料中由LU扫描仪产生的高质量的损伤图像与由X射线断层扫描产生的图像相似;但它们只能通过单面进入研究对象来获得。LU方法可以潜在地应用于现场的大型部件。
Damage induced in polymer composites by various impacts must be evaluated to predict a component’s post-impact strength and residual lifetime, especially when impacts occur in structures related to human safety (in aircraft, for example). X-ray tomography is the conventional standard to study an internal structure with high resolution. However, it is of little use when the impacted area cannot be extracted from a structure. In addition, X-ray tomography is expensive and time-consuming. Recently, we have demonstrated that a kHz-rate laser-ultrasound (LU) scanner is very efficient both for locating large defects and evaluating the material structure. Here, we show that high-quality images of damage produced by the LU scanner in impacted carbon-fiber reinforced polymer (CFRP) composites are similar to those produced by X-ray tomograms; but they can be obtained with only single-sided access to the object under study. Potentially, the LU method can be applied to large components in-situ.
