A Practical Fiber Optic Sensor to Monitor Resin Cure and Interphase Formation



Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, J H. VanZanten, Joy Dunkers, Richard~undefined~undefined~undefined~undefined~undefined Parnas


A fluorescent probe, covalently grafted to glass, can be used to study the glass/resin interphase region near the surface. A blue shift in fluorescence during resin cure can be monitored when the grafted dye is immersed in epoxy. The position of the fluorescence can be used to detect a difference between the bulk resin and interphase. To make the technique practical as a cure sensor, the dye can be grafted to a glass fiber optic.
