An aerofoil shaped body includes a plurality of longitudinal spars, an upper aerofoil cover, and a lower aerofoil cover. The spars and the covers are made of composite laminate material. One of the spars is integrally formed with one of the covers to form a spar-cover such that the composite laminate material of the spar extends continuously into the cover through a fold region created between the spar and the cover. The fold region has a fold axis extending substantially in the longitudinal direction, and the fold axis projected onto two orthogonal planes has curvature in both those planes.
