Abstract: A process for constructing a hybrid material part includes mixing a metal powder and a binder to form a compounded mixture, heating the compounded mixture, injecting the compounded mixture into a first mold to form a green part, and debinding the green part to form a brown part. The process further includes sintering the brown part to form a sintered part, and over-molding the sintered part with a plastic in a second mold of an injection molding machine to form the hybrid material part. A hybrid material pump part is disclosed as well.

Abstract: A variable displacement pump, and methods of manufacturing such systems are provided. The variable displacement pump can include a housing defining an inlet and an outlet, a rotor positioned between the inlet and the outlet, the rotor being configured to pump a liquid between the inlet and the outlet, and the rotor having a multiple of vane slots, a multiple of vanes, each disposed in a respective one of the multiple of vane slots, and a pendulum positioned between the rotor and the housing, the pendulum comprising a pendulum body and a stiffener, wherein the stiffener is located at least partially within the pendulum body, and wherein the rotor, the multiple of vanes, and the pendulum body are made of a polymer.

Abstract: An engine cover is disclosed that includes a contoured laminate defining a plurality of accessory holes configured to receive a plurality of accessories.
