摘要

在这项研究中，我们提出了一种基于银纳米颗粒的碳纤维增强塑料(CFRP)墨水的在线监测方法。在用预浸料蒸压法制备CFRP板并在材料上印刷导电路径后，我们通过光学显微镜研究了CFRP上印刷的银纳米颗粒油墨的导电路径。同时进行电阻测量的机械测试表明，使用专门设计用于促进弯曲下纤维间失效和分层的样品，可以检测到特定模式的失效。分层可以通过电通厚度测量和导电路径的电阻测量来检测和定位材料内部，从而可以检测表面裂纹。

Online monitoring of surface cracks and delaminations in carbon fiber/epoxy composites using silver nanoparticle based ink

Abstract In this study, we present an online-monitoring approach using silver nanoparticle based ink on carbon fiber reinforced plastics (CFRP). After production of CFRP plates in a prepreg autoclave process and printing conductive paths on the material, we investigate the conductive paths of printed silver nanoparticle-based ink on CFRP by light microscopy. Mechanical tests with simultaneous electrical resistance measurements demonstrate the possibility to detect particular modes of failure with samples specifically designed to promote inter-fiber failures and delaminations under bending. Delaminations can be detected and localized inside the material by electrical through-thickness measurements and resistance measurements of the conductive paths allow for surface crack detection.
