Abstract
A system and method are presented in which a flow of plastic is extruded to obtain nano-sized features by forming multiple laminated flow streams, flowing in parallel through the non-rotating extrusion system. Each of the parallel laminated flow streams are subjected to repeated steps in which the flows are compressed, divided, and overlapped to amplify the number of laminations. The parallel amplified laminated flows are rejoined to form a combined laminated output with nano-sized features. The die exit is formed to provide a tubular shape.
Claims12
A micro-layer tubular extrusion product, comprising:
- multiple solidified ribbon shaped flow streams each including multiple laminated flow streams arranged to flow in parallel, each solidified ribbon shaped flow stream having two ends, the two ends are opposing surfaces that are parallel to the flow stream,
- wherein one end of one solidified ribbon shaped flow stream is bonded to one end of another solidified ribbon shaped flow stream and the bonded multiple solidified ribbon shaped flow streams form the micro-layer tubular extrusion product, the ends of the respective ribbon-shaped flow streams which are bonded to another being the opposing surfaces that are parallel to the flow stream which are adjacent to and in direct contact with one another.
