Scarf connection for a wind turbine rotor blade

A method of joining first and second structures of a rotor blade of a wind turbine, the method comprising:

• arranging the first structure with the second structure at a scarf joint, the first structure constructed of a first composite material, the second structure constructed of a second composite material being different than the first composite material, the second structure comprising a plurality of layers, each of the plurality of layers of the second composite material comprising an end that terminates at the scarf joint;
• arranging a plurality of segments of a third composite material that is different than the first and second composite materials between the first and second composite materials at the scarf joint so as to completely wrap the ends of the plurality of layers of the second composite material with the plurality of segments of the third composite material, wherein the third composite material comprises at least one of a composite veil material, a biax composite material, or a chopped strand mat;
• and,
• infusing the scarf joint so as to join the first and second structures together.
