METODO DE APILADO PARA COMPONENTES NO PLANOS DE MATERIAL COMPUESTO

摘要

A method for laying-up the tapes (21, 23, 25) of a prepeg composite material in the 0º direction of a non-planar composite component on a suitable mould using an ATL machine comprising steps of: a) determining the trajectories of said tapes as modified trajectories of geodesic trajectories complying with the following conditions in their projections in an horizontal plane: that the radius of curvature R 2 of their curved segments is bigger than a predetermined value R min ; that the gap G 2p between two contiguous tapes is comprised between 0 and a predetermined value G max ; b) providing said modified trajectories to said ATL machine. A non-planar composite component such as an skin of an aircraft wing having the tapes in the 0° direction following trajectories complying with said conditions is also disclosed.
