    Abstract

    To adopt controlled heat treatment process for Piezo coatings on substrates viz., Aluminium and CFRP, a detailed study on ‘transient thermal analysis’ has been carried out using finite element analysis. Piezo coated Aluminium and CFRP has been modeled subjecting the top surface of the piezo to a process temperature of 180oC by spot heating for ten minutes, while the rest of the structure is maintained at room temperature. Due to conduction, heat gets transferred to substrate in both longitudinal and transverse direction. Purpose of this study is to observe the temperature distribution on the substrate along the in-plane and thickness direction of the piezo coating with respect to time. This evaluation is necessary to determine the minimum time of spot heating of piezo coating, to avoid over heating of the substrate which will degrade its property. Thermal stresses developed during the heating process were also determined under different boundary conditions. The geometry of the model was selected as per requirement of the final prototype device. It was analysed that the thermal stresses induced in the case of Aluminium substrate was higher than that induced in CFRP
