Abstract
A plurality of polymer layers are stacked together and subjected to a consolidation operation to generate an orthopaedic bearing component. Each layer is formed by longitudinally extending polymer fibers that are placed or woven together to define a predetermined orientation of the fibers.
The consolidation operation fuses the layers together while at the same time retaining the predetermined orientation of the fibers.
The consolidation operation fuses the layers together while at the same time retaining the predetermined orientation of the fibers.
