The deployment of optical fibre based sensor systems for process monitoring of advanced fibre reinforced organic matrix composites is reviewed. The focus is on thermosetting resins and the various optical and spectroscopy-based techniques that can be used to monitor the processing of these materials. Following brief consideration of the manufacturing methods commonly used in the production of thermoset based composites, a discussion is presented on sensor systems that can be used to facilitate real-time chemical process monitoring. Although the focus is on thermosets, the techniques described can be adapted for chemical monitoring of organic species in general.

“…Examples of areas of concern in this industrial sector are as follows. (i) The robustness and survivability of the sensor system [11]: The low attenuation characteristics of silica-based optical fibers makes them ideal for data transmission over long distances. However, these fibers and sensors tend to be brittle and hence adequate protection must be provided.…”

This paper reports on the design requirements and a range of specific concepts for optical fiber-based sensor protection systems that can be used in concrete structures. The designs range from sensor protection systems that are manufactured involving stainless steel, fiber reinforced composites and concrete. The feasibility of manufacturing the sensor protection systems using these materials is also demonstrated. A detailed finite element analysis was carried out to optimise the stainless steel-based sensor protection system for concrete. Experimental results involving the sensor protection system will be presented in Part 2 of this series of papers.

This report presents the results of a preliminary failure modes and effects analysis (FMEA) of a candidate design for the ITER Disruption Mitigation System. This candidate is the Massive Gas Injection System that provides machine protection in a plasma disruption event. The FMEA was quantified with "generic" component failure rate data as well as some data calculated from operating facilities, and the failure events were ranked for their criticality to system operation. v CONTENTS ABSTRACT
