FIELD: polymer materials.
SUBSTANCE: invention is directed to forming layered articles, in particular antenna reflectors. Method comprises laying layer-by-layer shell of an article, forming rigidity ribs using heat-expandable elastic tube, which is preliminarily twined with thread made from the shell material, whereupon elastic tube is laid on the shell surface, article is hardened, and elastic tube is removed.
EFFECT: increased strength of ribs thus allowing the number of plastic monolayers to be diminished without loss of mechanical strength.
