In this paper, a numerical study on the simulation of induction heating phenomenon for the bonding of carbon fiber reinforced polymer (CFRP) components is presented. Three different models have been developed to simulate the induction heating on a stiffened composite panel for the bonding of stringers to the skin. Indeed an electromagnetic model has been developed to evaluate the energy loss due to the Joule effect while a thermal model has been used to calculate the temperature distribution within the adhesive layer between skin and stringer. Then a structural model has been adopted to predict the ultimate failure load of the stiffened panel taking into account the degree of cure of the panel depending on the temperature distribution at interface between skin and stringers. Finally, a sensitivity analysis has been performed to evaluate the effects of the geometrical parameters of the stiffened composite panel and process parameters on the degree of cure of the adhesive at interface between skin and stringers.

Abstract
In this paper, a numerical study on the simulation of induction heating phenomenon for the bonding of carbon fiber reinforced polymer (CFRP) components is presented. Three different models have been developed to simulate the induction heating on a stiffened composite panel for the bonding of stringers to the skin. Indeed an electromagnetic model has been developed to evaluate the energy loss due to the Joule effect while a thermal model has been used to calculate the temperature distribution within the adhesive layer between skin and stringer. Then a structural model has been adopted to predict the ultimate failure load of the stiffened panel taking into account the degree of cure of the panel depending on the temperature distribution at interface between skin and stringers. Finally, a sensitivity analysis has been performed to evaluate the effects of the geometrical parameters of the stiffened composite panel and process parameters on the degree of cure of the adhesive at interface between skin and stringers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
