METHODS FOR MANUFACTURING WIND TURBINE ROTOR BLADE PANELS HAVING PRINTED GRID STRUCTURES

WIPO Patent Application WO/2019/103830

A3

A method for manufacturing a rotor blade panel of a wind turbine includes placing one or more fiber-reinforced outer skins into a mold of the rotor blade panel. The method also includes printing and depositing, via a computer numeric control (CNC) device, a plurality of rib members that form at least one three-dimensional (3- D) reinforcement grid structure onto an inner surface of the one or more fiber- reinforced outer skins. Further, the grid structure bonds to the one or more fiber- reinforced outer skins as the grid structure is deposited. Moreover, the method includes printing at least one additional feature into the grid structure.
