摘要

飞机复合材料壁板与金属壁板的连接是机身结构设计的重要研究内容。由于复合材料与金属之间性能存在差异，导致混合连接件服役状态下的应力难以预测。以碳纳米管（CNTs）和MXene薄膜为代表的新型纳米碳材料具有独特的纳米尺度结构和优异的物理性能。本文通过改进MXene/CNT复合薄膜传感器制备工艺，并将其应用于复合材料/ 金属连接结构健康监测，对服役过程中的混合连接结构进行全过程跟踪测试。结果表明，薄膜传感器在全过程监测响应与混合结构连接件时间应变曲线吻合，并且能够对混合连接结构失效精确预警，具有一定的工程意义。

Abstract

The connection between aircraft composite panels and metal panels is an important research topic in the fuselage structure design. Due to the differences in properties between composites and metals

resulting in the stress of hybrid connectors during service being difficult to predict. Novel carbon nanomaterials represented by carbon nanotubes (CNTs) and MXene films possess unique nanoscale structures and excellent physical properties. In this paper

by improving the preparation process of MXene/CNT composite film sensors and applying them to the health monitoring of composite/metal joint structures

a whole process tracking test of the hybrid joint structures during service is carried out. The results show that the monitoring responses of the thin film sensor throughout the process coincide with the stress–strain curve of the hybrid structure connectors

and it can give accurate early warnings of the failure of the hybrid connection structure

which has certain engineering significance.
