航空复合材料连接结构实时健康监测

Real-time Health Monitoring of Aviation Composite Connection Structure

随着复合材料在航空结构中的广泛应用,复合材料的研究也越来越深入。由于复合材料的特殊性,难以直接观察复合材料粘接结构和复合材料螺栓结构的使用状态。提出了一种新型的可对复合材料实时结构健康监测的MXene薄膜传感器制备技术。提出的制备方法经进一步加工处理可以得到性能优异的MXene传感器,通过碳基纳米传感器和MXene油墨传感器监测复合材料修复结构上不同位置的应变来进行复合材料结构健康监测。试验表明,碳基纳米传感器和MXene传感器为进一步了解修复结构的故障机制提供了一个有效和完整的监测过程。

With the widespread application of composite materials in aerospace structures, the research on composite materials has become more and more in-depth. Due to the particularity of composite materials, it is difficult to directly observe the state of use of composite material bonding structure and composite material bolt structure. A new type of MXene thin film sensor preparation technology that can monitor composite material real-time structural health is proposed. The proposed preparation method can be further processed to obtain the MXene sensor with excellent performance. The composite material structure health monitoring can be carried out by monitoring the strain at different positions on the composite repair structure through the carbon-based nano sensor and the MXene ink sensor. Experiments show that carbon-based nanosensors and MXene sensors provide an effective and complete monitoring process for further understanding of the failure mechanism of repaired structures.
