Abstract
A pulsed photoacoustic technique was used for generation of ultrasonic pulses along with optical detection inside a transparent polymer resin undergoing a curing reaction. The changes in acoustic parameters during the solidification process was measured and were found to agree with the accepted general model for the kinetics of the curing reaction for polyester and epoxy resins. The advantages of the acoustic characterization compared to the more common calorimetric techniques are considered.
