A method of manufacturing a blade component of rotor blade of a wind turbine includes providing a plurality of pultrusions constructed of one or more fibers or fiber bundles cured together via a resin material. The method also includes placing a protective cap over at least one end of one or more of the plurality of pultrusions. Further, the method includes heat treating a surface of the plurality of pultrusions while the protective cap remains over the at least one end. Moreover, the method includes removing the protective cap from the at least one end. The method further includes arranging the plurality of pultrusions in a mold of the blade component. In addition, the method includes infusing the plurality of pultrusions together so as to form the rotor blade component.
