一种纳米工程混合复合材料系统已经开发出来，在极低的碳纳米管（CNT）含量的集成损伤传感能力。所采用的简单喷涂技术提供了良好的空间控制和局部CNT沉积的可能性，特别是在纤维/基体界面附近，解决了与在纤维增强复合材料层压板中掺入纳米填料相关的传统问题，例如增加的树脂粘度和过滤效果。此外，所采用的喷雾技术具有良好的工业放大潜力。基于标准复合材料测试的原位损伤传感首次在使用极低碳纳米管负载（低于0.1wt%）的混合玻璃纤维/碳纳米管复合材料上得到证实并且显示出通过受控的CNT沉积到损伤易发区中来进行局部结构健康监测的巨大潜力。
A nanoengineered hybrid composite system has been developed, with integrated damage sensing capabilities at extremely low carbon nanotube (CNT) contents. The employed simple spray coating technique offers good spatial control and the possibility of localized CNT deposition, especially near the fibre/matrix interface, solving traditional problems associated with the incorporation of nanofillers in fibre-reinforced composite laminates such as increased resin viscosity and filtering effects. Moreover, the employed spraying technology has good potential for industrial scale-up. In situ damage sensing based on standard composite tests has been demonstrated for the first time on hybrid glass fibre/CNT composites using extremely low CNT loadings (below 0.1 wt.%) and shows great potential for localized structural health monitoring by controlled CNT deposition into damage prone zones.
