METHOD TO PRODUCE FLAKY MATERIALS FROM POLYMER TAPES ARRANGED IN ONE DIRECTION Russian patent published in 2011 - IPC B32B27/08 B29C70/04 F41H5/04 

FIELD: technological processes.

SUBSTANCE: invention relates to porous materials and to a method of flaky materials production from polymer tapes arranged in one direction. The flaky material is formed from at least two monolayers of polymer tapes. Tapes have shell and core structure. The method contains the following stages: formation of the first monolayer of polymer tapes by preliminary tensioning of polymer tapes and subsequent arrangement of polymer tapes under tension in parallel in one direction; formation of the second monolayer above the first monolayer in the same manner as the first monolayer was produced, laying at least two monolayers of polymer tapes are laid one onto the other so that the direction of polymer tapes is identical in each monolayer, and so that polymer tapes of each monolayer are displaced relative to the tapes of the adjacent monolayer arranged higher or lower than this monolayer; compaction of thus laid monolayers of polymer tapes to produce a flaky material.

EFFECT: invention provides for simple manufacturing of multilayer products.
