FIELD: technological processes.
SUBSTANCE: invention is related to method for manufacture of multilayer items by means of compression formation of multilayer portion of material. Multilayer portion of material with axis of symmetry consists of the first synthetic polymer and thin functional layer enclosed in the first polymer. Functional layer makes less than 20% of material portion volume. Multilayer portion of material is characterised by the fact that functional layer makes shell of rotary body around axis of symmetry. Distance from functional layer to axis of symmetry is alternating. Invention is also related to method for manufacture of axisymmetric multilayer portion of material.
EFFECT: invention makes it possible to adjust thickness of functional layer, provides for possibility to arrange layer of adhesive, to increase cohesion between layers and item strength, to reduce item cost.
