A Moineau style stator includes a helical reinforcement component that provides an internal helical cavity. A resilient liner is deployed on an inner surface of the helical reinforcement component. The helical reinforcement component includes a solder or braze material and is typically metallurgically bonded to an inner wall of a stator tube. In exemplary embodiments, the helical reinforcement component includes a composite mixture of solder and aggregate. Exemplary embodiments of this invention address the heat build up and subsequent elastomer breakdown in the lobes of prior arts stators by providing a helical reinforcement component. Solder reinforced stators tend to be less expensive to fabricate than reinforced stators of the prior art.

A Moineau style stator includes a helical cavity component having reinforced helical lobes. The lobes are reinforced with a three-dimensional network of physically bonded aggregate particles. The network of bonded aggregate provides a porous skeletal-like structural reinforcement. Pore volume between the bonded aggregate particles may optionally be partially or substantially filled with an elastomer. An elastomer liner is typically deployed on an inner surface of the helical lobes to promote a rotational interference fit with a rotor.

A mold for molding an expanded resin, wherein a silicone rubber layer (40) having a JIS-A hardness of 20 to 70 is formed as a heat-insulating layer at least on a part or the whole of the inner wall surface that forms a cavity (20) of a mold main body (10) which is for use in molding an expanded resin and which is made of an aluminum material. This mold for molding an expanded resin is effectively usable in molding expanded polystyrene or the like by a bead molding method, and can produce a molded product of an expanded resin with high thermal efficiency by virtue of high heat insulation performance. Further, the mold can be easily produced with good execution efficiency.

The present invention addresses the problem of providing: an electroconductive porous body that has a large specific surface area, that does not readily break under pressure, and that can be applied to a variety of applications; a solid polymer fuel cell; and a method for manufacturing an electroconductive porous body. This electroconductive porous body is obtained by aggregating a fibrous material having a first electroconductive material and a second electroconductive material that links spaces in the first electroconductive material, the electroconductive porous body having a specific surface area of 100 m2 / g or above, and a thickness retention rate of 60% or above after application of pressure at 2 MPa. Such an electroconductive porous body can be manufactured by spinning a spinning solution containing the first electroconductive material and a carbonizable organic material, forming a precursor fiber porous body in which precursor fibers are aggregated, and subsequently carbonizing the carbonizable organic material to obtain the second electroconductive material.

The invention relates to a related joint forming process of a conical metlbond composite material structure and an overall blank preformed unit. The shape of the conical metlbond composite material structure is unfolded and differentiated, and the related joint width of the preformed unit is taken as the basis of the size, thus a tablet prepressing mold can be designed and manufactured; the chargeamount of each preformed unit is calculated; metlbond premix compound is horizontally and evenly added in the preheated prepressing mold, a hydraulic press pressurizes on the preformed unit, demoulding is carried out after holding the temperature for 10-30 minutes; the preformed unit after demoulding is immediately bent into an arc preformed unit by a conical explorator; cooling is carried out for 15-30 minutes; the preformed unit is put in the preheated overall forming mold for related joint, the overall blank is obtained by sealing the preformed unit by a gum cover and pumping to be in vacuum. By adopting the process, one third of the metlbond premix compound can be saved in production, the production cost is greatly reduced; the original processing period of 4 days is reduced to 2.5 days, thus improving the production efficiency; the loading difficulty and labor intensity are lowered, the controllability of the process is improved, the thickness of the product is even and complete,and the stability of the product quality is greatly improved.
