本文是第一个三个描述监测纤维缠绕圆筒使用布拉格光栅传感器。第一部分介绍了技术问题和发展的标本与嵌入式光栅和热电偶。其目的是监测气缸制造过程中的温度和应变变化（见第二部分）和使用中的行为（见第三部分）。试样是纤维缠绕玻璃纤维增强环氧复合材料，因此必须解决两个技术问题：一是在制造过程中收集数据，二是在不损坏传感器的情况下将试样从芯轴上取下。这些都是通过设计一个特别适合分裂心轴和旋转之间的纤维缠绕机和复合材料圆筒制造接口。在传感器插入后，可以立即使用这种特殊适配的工具通过收集布拉格光栅波长和温度响应来监控制造过程。
This paper is the first of three describing the monitoring of filament wound cylinders using Bragg grating sensors. Part I describes the technological issues and the development of specimens instrumented with embedded gratings and thermocouples. The aim is to monitor the temperature and strain changes during cylinder manufacture (see Part II) and in-service behaviour (see Part III). Specimens are filament wound glass reinforced epoxy composites, so two technological problems have to be solved: one is to collect data during fabrication and the second is to remove the specimen from the mandrel without damaging the sensors. These were accomplished by design of a specially adapted split mandrel and a rotating interface between the filament winding machine and the composite cylinder in fabrication. Immediately after sensor insertion it was possible to monitor the fabrication process, by collecting Bragg grating wavelength and temperature response, using this specially adapted tooling.
