Abstract: Laminated wood tower including a plurality of curved modules attached to each other, where each curved module includes a plurality of layers, where each layer includes a plurality of laminated plies, and where a layer includes a first set of plies, where the first set of plies includes a plurality of plies arranged adjacent each other and where the wood grain is directed in a first direction, and a second set of plies, where the second set of plies includes one or more plies arranged adjacent each other and where the wood grain is directed in a second direction, where the first direction is perpendicular to the second direction. The advantage is that a self-supporting laminated wood tower can be obtained in an easy and cost-effective way.
Abstract: Rotor blade for a wind power plant. The rotor blade includes a plurality of curved laminated wooden modules attached to each other, where each curved laminated wooden module includes a plurality of laminated veneer lumber boards. Each curved laminated wooden module is curved in at least one direction, where each laminated veneer lumber board includes a first set of veneer plies, where the first set of veneer plies includes a plurality of veneer plies and where the wood grain is directed in a first direction, and a second set of veneer plies, where the second set of veneer plies includes a single veneer ply or several veneer plies arranged adjacent each other and where the direction of wood grain differs from the first direction. Beneficially, the rotor blade including curved laminated wooden modules can be obtained in an easy and cost-effective way. The rotor blade is further environmental friendly.
