Abstract
The flow and temperature of UV-curable resin illuminated with UV rays were measured, and it was investigated whether the flow of the resin is related to the heat generated by the chemical reaction in the resin. A system was developed for simultaneously measuring the flow and temperature of the resin using digital and infrared cameras, respectively. The flow was observed as a vector field obtained using a digital image correlation technique. Results indicated that the flow of UV-curable resin in the curing process was mainly related to the shrinkage of the resin and hardly related to its temperature.
