Summary :

This paper describes the induction heating system designs for spliced fiber reinforcement and the reinforcement performances. In the case of the reinforcement method using hot-melt adhesive, it is necessary to give the reinforcing assembly the precise temperature distribution. For this reason, the power transfer efficiency from the power source to the work object of the reinforcing assembly was investigated under practical induction heating conditions. Furthermore, the effect of each coil of the induction coils on the magnetic intensity generated in the part of the work object opposite the induction coils was examined. The transient temperature distribution of the work object could be obtained through simulation by designing the proper numbers of turns of wire, the setting positions of the induction coils and the dimension of electric power at a power source. The simulation results agreed approximately with the measured temperatures of the work objects. Through the proper thermal designs, the sandwich and heat-shrinkable-sleeve reinforcements were completed within 1 min., 30 sec. with good performances by supplying less than 26, 12-W of electric powers, respectively.
