ABSTRACT:
Apparatus for producing high modulus products. A polymer morphology or powdered metal is solid-state deformed under pressure through the rollers of an extrusion rolling die, at a temperature near but below its crystalline melting point, while controlling the extrusion rate and the rate of rotation of the rollers so that the rate of extrusion of the polymer or metal is substantially the same as the rate of rotation of the rolling die surface.
