N2 - A rheology sensor for monitoring the dynamic viscosity of a thermally curing resin is described. The complex shear modulus of the resin at 1 MHz is derived from the measured reflection coefficient of shear wave pulses at the resin surface. A special transducer-buffer assembly has been developed that operates at high temperature (T = 145°C) and provides a reference calibration signal. With this assembly, absolute determinations are made throughout the cure cycle of the real and imaginary components of the shear modulus. From the latter high-frequency dynamic viscosity is calculated. The results are compared with data obtained at low shear rates with a 10 Hz torque viscometer.
