INFLUENCE OF THE INDUCTION HEATING PROCESS ON A NANO-MODIFIED ADHESIVE FOR AUTOMOTIVE APPLICATIONS

The motivations of this study are due to the lack of information on this topic and to the different sensitivity and behaviour of the nano-particles compared to metal workpieces. While induction heating coupled with metal component has been widely studied, the induction heating process coupled with nanoparticle embedded in the adhesive is at an early stage. This latter process is based on properly shaped inductor coils and properly set electromagnetic field control unit. In this paper, the sensitivity to some process parameters, in the case of the magnetite nanoparticles dispersed in the HMA, has been studied. The parameters analysed in this experimental activity are: the shape of the coil, diameter of the pipe coil, frequency of the inductor and induced current of the inductor. The parameter used to measure this sensitivity is the time needed to separate a single lap joint specimen (SLJ
