Method and system for continuous in situ monitoring of viscosity

An apparatus and method for in situ monitoring the viscosity and cure of resins using viscosity dependent fluorescence uses a fiber optic waveguide to introduce light to the resin of a wavelength exciting fluorescence and to conduct the emitted light to a monitor. The emitted light parameters correl...

Beschreibung
Zusammenfassung:	An apparatus and method for in situ monitoring the viscosity and cure of resins using viscosity dependent fluorescence uses a fiber optic waveguide to introduce light to the resin of a wavelength exciting fluorescence and to conduct the emitted light to a monitor. The emitted light parameters correlate to the viscosity and cure conditions of the resin. The apparatus and method may be used to control composite construction and to provide information on the in service condition of composites.
