抄録

While studying the ultrasonic joining of poly(ethylene terephthalate) (PET) films, we measured the temperature increase at the interface between two films during ultrasonic joining. To measure the temperature, we developed an experimental set-up consisting of an ultrasonic welder and a radiation thermometer, and measured the time dependence of the temperature changes at the interface. There was an exothermic reaction while the films were joined. We inspected cross sections of the joined parts, and found an intermediate layer. This intermediate layer is an element of a unique structure involved in ultrasonic joining. Conceivably, in the intermediate layer, PET molecules are involved in Brownian motion.
