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 (<1MW/cm2) of T700 CFRP. The dynamics of the process is observed by high speed camera (200...$28.00

Presented at ICALEO 2013
Continuous carbon fibre reinforced composites (CFRP) are recognized as having a significant lightweight construction potential for a wide variety of industrial applications. However, a today‘s barrier for a comprehensive dissemination of CFRP structures is the lack of economic, quick and reliable manufacture processes, e.g. the cutting and tr...$28.00

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...$28.00
