Abstract: A trailing edge protective cap for a rotor blade of a wind turbine and method of manufacturing same is disclosed. The method includes infusing a first material onto a first mold so as to form a first part having a length. While the first part is still in the first mold, the method may also include placing a second mold onto the first part. The method may then include infusing a second material onto the second mold and at least a portion of the first part so as to form a second part having a length. The first and second parts may then be joined or infused together along a portion their respective lengths so as to form the protective cap, wherein the protective cap includes a joined section and an open section.

Abstract: In one aspect, a rotor blade for a wind turbine includes a body extending between a root end and a tip end. The body may include a root portion extending from the root end. The root portion may include an inner surface defining an inner circumference. In addition, the rotor blade may include a root stiffener disposed at least partially within the root portion of the body. The root stiffener may include a plurality of arms extending radially from the inner surface and may be configured to extend circumferentially around only a portion of the inner circumference of the root portion.
