120104 Simultaneous Measurement of Temperature and Movement of Ultraviolet Curable Resin during Curing Process

Abstract

The relationship between the temperature and movement of ultraviolet (UV) curable resin illuminated at UV ray is investigated. A system is developed for simultaneously measuring temperature and movement of the resin. The temperature and movement are measured using infrared and digital cameras, respectively. The movement is shown as streamline patterns drawn on the basic of velocity obtained using a digital image correlation technique. Moreover, the movement is represented as the paths of particles mixed in the resin obtained using a digital image correlation technique. Results indicate that the movement of UV curable resin in curing process mainly relates to the shrinkage of the resin and hardly to the temperature of the resin.
