Abstract: A method of forming a rotor blade includes positioning first dry skin layer(s) in a first mold. The method also includes placing a wedge-shaped core material having a mounting surface atop the first dry skin(s) in the first mold at a trailing edge end of the rotor blade. The method further includes infusing the first dry skin layer(s) and the core material together via a resin material to form a first shell member. The method includes applying an adhesive onto the mounting surface and then placing a second mold with a second shell member arranged therein atop the first mold containing the first shell member to form the rotor blade such that a portion of the second shell member rests atop the mounting surface. Thus, the method includes securing the shell members together via the adhesive, wherein the core material supports the trailing edge end of the rotor blade.
