Claim 19:
20. A method of controlling a plasma heat treating process for forming a pultrusion for use in manufacturing a blade component of rotor blade of a wind turbine, the method comprising:
providing the pultrusion of one or more fibers or fiber bundles cured together via a resin material;
placing a protective cap over at least one end of the pultrusion, the protective cap conforming to a shape of the at least one end; and,
applying a plasma treating process to at least one surface of the pultrusion while simultaneously blocking heat to the at least one end of the pultrusion with the protective cap during the plasma treating process, the at least one end of the pultrusion defining a cross-sectional thickness that is less than an overall cross-sectional thickness of the pultrusion.
