Abstract
A composite ring includes a first region including a first polymeric material; a second region including a second polymeric material; and an interfacial region defining a compositional gradient between the first region and the second region; wherein a wear resistance of the first region is different from a wear resistance of the second region. A composite bearing includes a first layer including a first polymeric material and a first filler; a second layer disposed on the first layer, the second layer including a second polymeric material and a second filler; and an interfacial region defining a compositional gradient between the first layer and the second layer, wherein a wear resistance of the first layer is greater than a wear resistance of the second layer, and wherein a mechanical strength of the second layer is greater than a mechanical strength of the first layer.
