Claim 0:
1. A method comprising preparing a composite material from a solid polymeric binder and a solid filler by feeding into an extruder the solid polymeric binder at a first feed rate and the solid filler at a second feed rate, the extruder (a) melting the solid polymeric binder, (b) mixing the melted solid polymeric binder with the solid filler, and (c) extruding an extrudate of the solid polymeric binder and solid filler to form the composite material, the composite material having a binder to filler ratio determined by the first feed rate and second feed rate;
wherein the solid polymeric binder and solid filler have different densities and feeding the solid polymeric binder at the first feed rate and the solid filler at the second feed rate distributes the solid filler substantially homogeneously throughout the composite material.
