1. A method of fabricating a stator for a downhole motor, the method comprising:

  • providing a stator tube having an interior surface;

    applying a bonding agent to the interior surface of the stator tube;

    positioning a mandrel within the stator tube, the mandrel having an outer geometry that is complimentary to a desired inner geometry for the stator;

    introducing a reinforcing material into the stator tube to fill space between the mandrel and the interior surface of the stator tube;

    solidifying the reinforcing material to bond the reinforcing material to the interior surface of the stator tube; and

    removing the mandrel from the bonded stator tube and reinforcing material;

    thereby fabricating the stator.
