- Tensile damage monitoring at different positions of double bolt structure by ultrafiltration membrane/buckypaper sensor Lu Zhang Yunqi Xie Xiaoyu Cui Shaowei Lu Xingliang Li Ying Wang Wei Li Jilun Hou Xiaoqiang Wang Polymer Composites AbstractMulti‐bolted composite laminates are popular in various fields. Under different working conditions, it is a serious problem to produce different kinds and extent of damage at the joints. Real‐time monitoring of it is a challenging task. The objective of this artical is to use ultrafiltration membrane/buckypaper sensor to monitor the health status of the structure at different positions in the tensile environment. Firstly, the aperture ratio is selected by tensile test, and the feasibility of ultrafiltration membrane/buckypaper sensor to monitor the bolt structure and the different response degree to different strains are verified. Then, ultrafiltration membrane/buckypaper sensor layout position is designed, and the signal response of the sensor at different positions is analyzed. The damage degree and form of different bolts are visualized by ΔR/R0 change, and the SEM scanning diagram is used for auxiliary verification. The results show that The sensor can monitor the damage condition and damage form at different positions of the double bolt structure laminate in real time. Based on this method, it can be used to study the damage behavior of more complex multi‐bolt structure under tensile environment.Highlights Ultrafiltration membrane/buckypaper sensor was prepared by a simple and efficient process. The pore structure of the ultrafiltration membrane integrates the sensor with the double bolt structure. Monitor the different damage forms of double bolt structure caused by external load. Monitor the different degrees of strain and crack propagation stage of the double bolt structure. 10.1002/pc.28751 http://onlinelibrary.wiley.com/termsAndConditions#vor
