Resin cure monitoring fibre optic sensors

Fibre Optic Sensor to Monitor Resin Cure... [Pg.393]

Applications of the fibre optics transmittance or ATR probe are in quality control, reaction monitoring, skin analysis, goods-in checking, analysis at high and low temperature, radioactive or sterile conditions, and hazardous environments. Applications of the reflectance probe are for turbid liquids, powders, surface coatings, textiles, etc. By using an on-line remote spectrophotometer, real-time information is gathered about a chemical process stream (liquids, films, polymer melts, etc.), as often as necessary and without the need to collect samples. This determines more reliable process control. Remote spectroscopy costs less to maintain and operate than traditional techniques. Fernando et al. [48] have compared different types of optical fibre sensors to monitor the cure of an epoxy resin system. [Pg.678]

A comparative study is presented for different types of optical fibre sensor developed to monitor the cure of an epoxy resin system. The sensors were based on transmission spectroscopy, evanescent wave spectroscopy and refractive index monitoring. 19 refs. [Pg.110]
