Structural adhesives have utilized different methods for accelerating cure and development of handling strength and final properties. These different methods have included fast curing chemistries, heated presses, microwave, radio frequency, high velocity hot air, and induction heating. Each method has particular advantages which the processor can use to maximize productivity and quality. This paper examines and reports on induction heating and its application for bonding of thermoplastics and composites. Induction heating has had good acceptance in bonding applications where metal substrates are involved. Automotive hem flange bonding has been a particularly successful application of induction heating. With metal bonding, the substrate is heated by the electromagnetic field generated by a current passing through an induction coil. Heating to cure temperatures occurs within fractions of a second and temperatures can easily surpass the limits of any organic adhesive.
