Abstract

A novel tubular or profile shapes of co-extruded multilayer polymers. These materials contain tens to thousands of layers of milli-, micro- to nano- polymer layers. These new shapes contain contiguous layers of milli- to nano- polymer layers in three dimensions and these contiguous layers may be twisted or turned to further expand the potential microlayer geometries.

Claims (5)

1. A method for creating multilayered products comprising merging multiple streams to form contiguous layers without weld lines of a tubular or annular microlayered composite, wherein one or more layers of said tubular microlayered composite contain fibers or particles.

2. A method according to claim 1 , wherein said tubular microlayered composite contains fibers.

3. A method according to claim 1 , wherein said tubular microlayered composite contains wood fibers or particles.

4. A method according to claim 1 , wherein said tubular microlayered composite contains clay particles.

5. A method according to claim 1 , wherein said tubular microlayered composite contains nanocellulose fibers or particles.
