A lightning and corrosion protection arrangement for a joint between an outer metallic part () and an aircraft structural component () completely or partially made of CFRP by means of a row of metallic rivets (), that comprise inner and outer metallic layers () and an intermediate dielectric layer (), the inner metallic layer () in contact with said structural component () being thinner and bigger than the outer metallic layer () in contact with the metallic part (), the intermediate dielectric layer () extending in an area bigger than the area of the foot () of the metallic part () by a predetermined minimum linear distance Dbetween its edges, the outer metallic layer () extending in an area bigger than the area of the intermediate dielectric layer () by a predetermined minimum linear distance Dbetween its edges.

Lightning and corrosion protection arrangement in an aircraft structural component

A method for laying-up the tapes of a prepeg composite material in the 0&#xb0; 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 Rof their curved segments is bigger than a predetermined value R; that the gap Gbetween two contiguous tapes is comprised between 0 and a predetermined value G; 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&#xb0; direction following trajectories complying with conditions described.
