Abstract (en)
[origin: WO2014065718A1] The present invention regards a structurally integrated curved structure (13, 13', 13'') comprising a curved transition region (15) being defined between a tip section (42) and a root section (11, 21), an upper and lower composite skin (27, 29) comprising an inner surface (45) fixed to a substructure (31) of said transition region (15), the substructure (31) and skins (27, 29) are, during use of the structure (13, 13', 13''), subjected to a bending moment (M), each skin (27, 29) of said transition region (15) comprises elongated reinforcement fiber-like elements. The lower composite skin (29) comprises reinforcing fibersand/or nano tubes(41, 43), which are oriented transverse to the inner surface (45). The invention also regard sa method for producing the structurally integrated curved structure (13, 13', 13'').
