ABSTRACT:
A fluid handling device such as a helicoidal pump or motor having a stator formed by an elastomer material in which a plurality of fibers are encapsulated. Preferably, the fibers form a network of interlaced fibers extending in two or more directions. The fiber network preferably forms multiple layers of flexible fabric encircling the stator axis. In addition, a group of the fibers can extend radially through the fabric layers. The fibers increase the strength and stiffness of the elastomer and also create heat conduction paths that improve the heat transfer within the stator core, thereby preventing overheating of the elastomer.
