Abstract: A method of reinforcing a laminated wing skin (10) for an aircraft. The method comprises laying-up a plurality of fibers to form the laminated wing skin (10). A composite reinforcement member (14) is positioned on a surface (16) of the laminated skin (10) and one or more further layers are laid up so as to enclose the composite reinforcing member (14) at a position adjacent one surface of the laminated skin (10).

Abstract: The method of constructing a skin for a member 30 of a body such as an aircraft comprises providing from a multi-axial fabric first and second pieces A, A1 shaped to correspond respectively to the shape of the member 30 to be covered by the skin and to the shape of a similar member 32 on the opposite side of the body, and inverting one of the pieces and placing it on the other. The method may include providing third and fourth pieces B, B1 from multi-axial fabric shaped to correspond respectively to the shape of the member 30 to be covered by the skin and to the shape of the similar member 32 on the opposite side of the body and inverting one of the third and fourth pieces B, B1 and placing it on the other to form a skin for the similar member.

Abstract: A method of constructing a composite material which comprises a laminate of plies comprising a warp dominated ply and a weft dominated ply, includes arranging first and second pieces 10,12 of material alongside each other with a recess 20 being defined at least partly by a warp dominated ply 14 so that parts 16,18 thereof form a lap joint 21 which is received at least partly in a recess 20 formed in or by a warp dominated or other ply, and arranging at least part 12a of one of said first and second pieces of material 10,12 in said recess 20 so as to form lap joint 21 with part 10a of the other of the first and second pieces of material 10,12. The parts 10a, 12a of said first and second pieces of material include weft dominated plies 16,18.
