Abstract

ABSTRACT There are currently little widely used structural health monitoring (SHM) techniques for structural adhesive joints. In this study, integrated fibre Bragg grating (FBG) sensors are used to examine the structural integrity and reliability of functional adhesive joints. There is an even greater demand for structural monitoring during operation or quality control of adhesive joints during production as more industries embrace high performance structural adhesives in fail-safe designs. Smartroof® photovoltaic (PV) roof tiles are used in this study to validate a real-time health monitoring of the adhesive connection between the PV glass plate and the polymer frame. A structural epoxy and a modified siloxane (MS) polymer are assessed. To assure measurement accuracy and to provide a better understanding of the strain sensing mechanism, the data is qualitatively compared with a finite element model. It is demonstrated that using embedded FBG sensors is accurate and adequate for in situ real-time structural health monitoring. Nevertheless, it remains difficult to ensure and manage the fibre’s position in the adhesive layer.

Cerasol®屋顶瓦片结构健康监测与嵌入式光纤光栅传感器

目前，广泛应用的结构粘接健康监测技术很少。在本研究中，使用集成光纤布拉格光栅(FBG)传感器来检测功能粘合接头的结构完整性和可靠性。随着越来越多的行业在故障安全设计中采用高性能结构粘合剂，在操作过程中对结构监测或生产过程中粘合接头的质量控制的需求也越来越大。在本研究中使用了Smartroof®光伏(PV)屋顶瓦片，以验证光伏玻璃板和聚合物框架之间的粘合剂连接的实时健康监测。对结构环氧树脂和改性硅氧烷(MS)聚合物进行了评价。为了保证测量精度和更好地理解应变传感机制，将数据与有限元模型进行定性比较。结果表明，采用嵌入式光纤光栅传感器对结构进行现场实时健康监测是准确可行的。然而，要确保和管理纤维在粘合层中的位置仍然很困难。
