1608 Flow Analysis of Ultraviolet Curable Resin during Curing Process Using Particle Tracking Velocimetry : Effect of Stiffness of Mold Bottom on Flow

Abstract

This study deals with the movement of ultraviolet (UV) curable resm illuminated at UV ray The movement is observed as particle trajectory patterns obtained using a particle tracking velocimetry technique The specimens consist of glass plates, acrylic plates, vinyl tape and UV curing resin m liquid form with acrylic powder. The specimens are illuminated with UV rays downwards from the upper side of the specimens, and the images of the resin in curing process are captured at a constant time interval using a digital camera Results indicate that the movement of UV curable resin in curing process is affected by the stiffness of the bottom of molds.
