Abstract:
1. A method of fabricating a Moineau style stator, the method comprising: (a) deploying a stator core substantially coaxially into a stator tube, the stator core having at least one helical lobe on an outer surface thereof such that a helical cavity is formed between the stator core and the stator tube; (b) forming a helical reinforcement component in the helical cavity, the helical reinforcement component including a composite mixture of a metallic or ceramic filler material deployed in a solder matrix material, wherein the melting temperature of the solder matrix material is less than the melting temperature of the filler material; (c) removing the stator core from the helical reinforcement component; and (d) forming a resilient liner on an inner surface of the helical reinforcement component.
