Abstract Structural health monitoring (SHM) of chemical penetration in composites is a critical issue for their durability as composite storage. Current methods are either complicated or expensive. Besides, the wired sensing system introduces defects in the composite structure. Herein, we present a novel wireless sensing design for detecting aggressive chemicals in composite reservoirs. Remarkably, the sensing system used in this work is cost-effective and easy to be configured. In this study, we used Radio Frequency Identification (RFID) as wireless sensing technology. A sensor embedded composite panel was prepared and tested in a harsh environment, 30 wt% H2SO4. Additionally, we modified an RFID tag with conductive nanocomposite for the aim of selective sensing. We found that the RFID tags are working well as sensors for detecting the chemical penetration in composites. Compared with conventional color-based methods, the presented novel wireless sensing method provides a much earlier warning signal for chemical penetration.

用于复合材料耐久性研究的新型无线传感设计

摘要 复合材料中化学物质渗透的结构健康监测（SHM）是其作为复合材料存储耐久性的关键问题。当前的方法要么复杂要么昂贵。此外，有线传感系统在复合结构中引入了缺陷。在此，我们提出了一种新颖的无线传感设计，用于检测复合储层中的腐蚀性化学物质。值得注意的是，这项工作中使用的传感系统具有成本效益且易于配置。在这项研究中，我们使用射频识别 (RFID) 作为无线传感技术。制备了传感器嵌入复合板，并在 30 wt% H2SO4 的恶劣环境中进行了测试。此外，我们用导电纳米复合材料修改了 RFID 标签，以实现选择性传感。我们发现 RFID 标签可以很好地用作检测复合材料中化学渗透的传感器。与传统的基于颜色的方法相比，所提出的新型无线传感方法为化学渗透提供了更早的警告信号。
