    Presented at ICALEO 2013

    Carbon-fiber-reinforced polymers are increasingly used especially in structural parts for new aircraft. However, laser machining is not well implemented for cutting or drilling because significant collaterals effects remain. In this paper, we propose a study of laser-matter interaction at moderate flows (

    Presented at ICALEO 2013

    Dissimilar joining of titanium to aluminum is required for several purposes in automotive and aerospace industries. Nevertheless, a number of issues arise due to their different properties, in terms of crystal micro structure, melting point, heat conductivity and coefficient of linear expansion. In addition, brittle intermetallic formation is induced at the interface, thus affecting the...
