Submitted Abstract

There is an increasing demand for integrated products which combine specific, complementary ¿properties of dissimilar materials, in particular polymers and metals. These hybrid miniaturized ¿structures offer higher strength, ductility and physiochemical resistance, which is crucial for ¿materials used in automotive industry. The main challenges in developing the new products entail ¿manufacturing light-weight, small, and gas tight parts at competitive production cost.¿This project proposes an innovative, environmentally-friendly laser based thermal joining process ¿that enhances the physiochemical susceptibility of the material surfaces to be used in sensors application. ¿However, we still face many unsolved questions: how to obtain an optimal metal-polymer joining ¿technology? How does the surface treatment of metal and polymer surfaces influence the bonding ¿characteristics? Which properties can be accomplished? To answer these questions variety of microstructural characterization techniques (SEM, XRD and XPS) plus mechanical testing have been foreseen to investigate the mechanism of metal-polymer joining.As a result of metal-polymer joining mechanism determination, this AFR PPP project will investigate the effect of alternative surface treatments to enhance the ¿physiochemical susceptibility of the material surfaces.¿ Furthermore, other parameters such as the effect of ultrasonic vibration on the bonding strength and the durability of joint is going to be studied.Our industrial partner will play a decisive role in the design and demonstration of these new ¿products according to market demand. The innovative know-how will finally enable to produce novel ¿integrated products with strong potential for scale-up industrial production.¿
