Abstract: The invention relates to a method for designing a composite material part with a curved surface (65) to which a plurality of stiffening elements will be joined, in which the design of a 3D fabric model comprises the following steps: generating a planar surface (63) developed in 2D of the surface (65) of the curved part in 3D as well as the same geometric references (71) in 2D as the references (51) of the surface in 3D; associating the surface (63) developed in 2D and the surface (65) in 3D as well as their geometric references (71, 51), such that any action in one of them is reflected in the other; initially computing the fabric model in the surface (63) developed in 2D; carrying out any subsequent modification of the fabric model either in the surface (63) developed in 2D or in the surface (65) in 3D.

Abstract: A method for laying-up the tapes of a prepeg composite material in the 0° direction of a non-planar composite component on a suitable mold using an ATL machine includes the steps of: a) determining the trajectories of the tapes as modified trajectories of geodesic trajectories complying with the following conditions in their projections in an horizontal plane: that the curvature radius R2 of their curved segments is bigger than a predetermined value Rmin; that the gap G2p between two contiguous tapes is comprised between 0 and a predetermined value Gmax; and b) providing modified trajectories to the ATL machine. The invention also refers to a non-planar composite component such as an skin of an aircraft wing having the tapes in the 0° direction following trajectories complying with conditions described.
