Abstract:
Fresnel refractometry was used to follow the changes in the refractive index
during the isothermal curing of a simple difunctional epoxy resin, a commercial
formulated multifunctional epoxy blend, and the same two resin systems modified
by the addition of multiwalled carbon nanotubes. The refractive index change,
monitored via an embedded optical fiber, was correlated with the degree of cure
established from isothermal differential scanning calorimetry measurements. A
good correlation was established in all cases, indicating the potential of the
technique to be used for online cure monitoring in thermosetting resin carbon
nanocomposites.
