Abstract: A system for manufacturing a panel includes a forming assembly having opposing press plates and at least one platen assembly arranged between the opposing press plates. The platen assembly includes first and second platens connected together via at least one elastic deformable member. Further, the forming assembly is operable in a heating mode and a cooling mode. Moreover, the first platen is maintained at a predetermined temperature range during each of the heating and cooling modes. During the heating mode, the elastic deformable member(s) is compressed such that the first and second platens contact each other. As such, one or more layers of material to be consolidated are held by the forming assembly as the forming assembly applies heat and pressure to the layer(s), thereby consolidating the panel.

Abstract: Systems and methods for joining blade components of a rotor blade are provided. A method includes positioning a first blade component and a second blade component such that a joint location of the first blade component and a joint location of the second blade component are proximate each other. The method further includes applying a force to an outer surface of the second blade component and an opposing force to an inner surface of the second blade component. The force and opposing force maintain an aerodynamic contour of the second blade component. The method further includes connecting the joint location of the first blade component and the joint location of the second blade component together.

Abstract: A method for manufacturing a rotor blade panel of a wind turbine includes placing a mold of the rotor blade panel relative to a computer numeric control (CNC) device. The method also includes forming one or more fiber-reinforced outer skins in the mold. The method also includes printing and depositing, via the CNC device, printing and depositing, via the CNC device, a plurality of rib members that intersect to form at least one three-dimensional (3-D) reinforcement grid structure onto an inner surface of the one or more fiber-reinforced outer skins before the one or more fiber-reinforced outer skins have cooled from forming. Further, the grid structure bonds to the fiber-reinforced outer skin(s) as the structure is deposited. In addition, the plurality of rib members include, at least, a first rib member extending in a first direction and a second rib member extending in a different, second direction. Moreover, the first rib member has a varying height along a length thereof.

Abstract: A rotor blade for a wind turbine may generally include a first blade component formed from a first fiber-reinforced composite including a first thermoplastic resin material and a second blade component configured to be coupled to the first blade component at a joint interface. The second blade component may be formed from a second fiber-reinforced composite including a second thermoplastic resin material, wherein the second thermoplastic resin material differs from the first thermoplastic resin material. The rotor blade may also include an additional layer(s) of thermoplastic resin material positioned on or integrated into the second fiber-reinforced composite at the joint interface that differs from the second thermoplastic resin material. Moreover, the first thermoplastic resin material of the first fiber-reinforced composite may be welded to the additional layer(s) of the thermoplastic resin material to form a welded joint at the joint interface between the first and second blade components.
