dc.description.abstractRheological behavior of thermoset/thermoplastic blends of epoxy/polyethersulphone (PES) was monitored
during curing of the epoxy resin. During the isothermal curing of the mixture, a fluctuation in viscosity just
before the abrupt viscosity increase was observed. This fluctuation is found to be due to the phase separation
of PES from the matrix epoxy resin during the curing. The experimentally observed viscosity fluctuation
is simulated with a simple two phase suspension model in terms of the increase in domain size. The viscosity
profiles obtained experimentally at different isothermal curing temperatures are in good agreement
with the predictions from the simple model taking into account the viscosity change due to the growth of
PES domain and the network formation of the epoxy matrix.
