Abstract
Methods of manufacturing rotor blade components for a wind turbine and rotor blade components produced in accordance with such methods are disclosed. In one embodiment, the method generally includes providing a mold of the rotor blade component; coating at least a portion of an interior surface of the mold with an elastomeric material; inserting impletion material within the mold so as to at least partially reduce an open internal volume within the mold; inserting a foam material within the mold; and, removing the rotor blade component from the mold, wherein the elastomeric material forms a cover skin around at least a portion of the rotor blade component. In an alternative embodiment, the method includes providing at least one support member defining a profile for the rotor blade component on a mold surface; coating at least a portion of the support member with an elastomeric material; and, allowing the elastomeric material to cure on the mold surface so as to form the rotor blade component.
