Time Determination

A method for real-time determination of the percent cure of epoxies via in situ fiber-optic Raman spectroscopy has been developed. This method utilizes a probe design developed for real-time monitoring of polymer curing and multivariate analysis to interpret the data and determine percent cure. This method was demonstrated to be reliable to ±0.54% of cure in laboratory samples over a 50–99% cure range. A preliminary study measuring cure percentage in an industrial, glass-reinforced composite has been shown to be reliable to ±0.82% in the 40–90% cure range.

Moisture Sensor

Fiber optic sensors for monitoring moisture, temperature and trace hydrogen peroxide have been developed in DIAL/MSU. The moisture sensor responds to moisture changes from RH = 4% to RH < 95% in the tested range. The temperature sensor can sense temperature from room temperature 22 °C to 90 °C in the tested range. The hydrogen peroxide sensor can detect/monitor hydrogen peroxide in an aqueous solution down to 10 ppb. Techniques have been developed for deploying the fiber optic sensors to the gas channels and the Nafion membrane of a PEM fuel, cell. These sensors will be tested for in situ, real-time monitoring of the operation of a PEM fuel cell with a fuel cell test system developed by CAVS/MSU. The principle of the sensors and test results of the sensors will be presented.
