METHOD FOR BONDING OUTER AND INNER CYLINDRICAL BONDIES

摘要

PURPOSE: To uniformly and strongly bond a different kind of materials, for example, FRP and metal over a wide bonding area with high reliability. ;CONSTITUTION: A main electrode 7 is arranged to the outside of an FRP shaft part 2 into which a metal yoke part 3 is inserted under pressure and an earth electrode is connected to the yoke part 3. A current is supplied across the main electrode 7 and the shaft part 2 in such a state that an electric insulating almost cylindrical spacer 11 gradually increased in thickness as approaching the earth electrode is inserted in the gap between them to perform dielectric heating. The rubber insulator 6 preliminarily vulcanized to be bonded to the outer peripheral surface of the yoke part 3 is subjected to dielectric heating and the heating reaction type adhesive preliminarily applied to the inner peripheral surface of the shaft part 2 is reacted to strongly bond the shaft part 2 and the yoke part 3 through the insulator 6.;COPYRIGHT: (C)1996,JPO
