研究了碳/环氧复合材料在层间剪切试验过程中的原位损伤传感问题。除了直接监测机织织物碳/环氧基准层压板外，还评估了通过喷涂层技术将碳纳米管(CNT)引入这些碳纤维织物以进行损伤传感的情况。与之前的研究相比，我们观察到了非常不同的感知行为，这被认为对实际应用更有用。贯通厚度测量显示，由于接触面积和导电路径的减少，参照物和碳纳米管修饰样品的电阻率都不断增加。并对引入的碳纳米管网络在界面区域的作用进行了比较和分析。
The in-situ damage sensing of carbon/epoxy composites during interlaminar shear testing is investigated. Next to direct monitoring of woven fabric carbon/epoxy reference laminates, the introduction of carbon nanotubes (CNTs) onto these carbon fibre fabrics via a spray coating technique for damage sensing is evaluated. We observed very different sensing behaviour compared to previous studies, which is believed to be more useful for real applications. Through-thickness measurements showed for both reference and CNT modified specimens a continuous increase in electrical resistivity, due to reduced contact areas and conductive pathways. The effect of the introduced CNT network at the interfacial region is also been compared and analysed.
