这是一项新颖的研究，旨在通过类似于老鼠胡须的触觉胡须传感器在复合材料表面上快速移动，从而检测复合材料中几乎不可见的冲击损伤 (BVID) 的可能性。对准各向同性复合材料板进行了一系列落塔低速冲击试验。该板由单向 T800 碳/MTM49-3 环氧树脂预浸料制成，堆叠顺序为 [45/0/90/−45]4S。用肉眼观察样品表面并没有发现任何明显的损坏，只是表面上有一个小凹痕，不同的冲击能量水平没有明显的差异。超声C扫描观察表明，在所有冲击能级中都存在BVID，并且随着冲击能级的增加，损伤尺寸有增大的趋势。使用支持向量机分类器根据振动特性对从晶须传感器收集的数据进行分析，以识别受影响的区域并对影响严重程度进行分类。据观察，在对 13 个胡须接触进行训练后，BVID 严重程度可以以 100% 的准确度进行分类。这提供了一种新的 BVID 检测技术，具有很高的自动化潜力和高可靠性，可以用作替代方案或与现有检测系统结合使用。
This is a novel investigation on the possibility of detecting barely visible impact damage (BVID) in composite materials by whisking across the surface via tactile whisker sensors that resemble rats’ whiskers. A series of drop tower low-velocity impact tests were performed on quasi-isotropic composite plates. The plates were made from unidirectional T800 carbon/MTM49-3 epoxy prepregs with the stacking sequence of [45/0/90/−45]4S. Investigating the specimens’ surface by the naked eye does not reveal any significant damage, rather than a small dent on the surface, with no tangible difference in the different impact energy levels. Ultrasonic C-scan observations showed the existence of BVID in all the impact energy levels, with an increasing trend in the damage size by increasing the impact energy level. The collected data from whisker sensors were analyzed using the support vector machine classifier, based on their vibrational properties, to identify the impacted region and classify the impact severity. It was observed that after training for 13 whisker contacts, the BVID severity can be classified with an accuracy of 100%. This is offering a new BVID detection technique, with a high potential for automation and high reliability that can be used as an alternative or combined with available inspection systems.
