Abstract

This paper deals with the change of joint geometry of non-ferrous metal sheets and composite plates reinforced with bi-directional glass and carbon fiber by thermal drilling due to the effect of different drilling strategy. Joints formed by direct and sequential drilling were tested. Sequential drilling represents a convenient way to minimize delamination of layered composites during joining.
