COMPOSITE HOLLOW SHELL MANUFACTURING METHOD Russian patent published in 2021 - IPC E04H12/02 B28B21/48 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to composite supports, spatial structures used for arrangement of light-signal equipment, advertisement, power transmission lines, communication equipment, etc. Method of composite hollow shell manufacturing consists in production of composite material wound on forming element, wherein for composite support composite material is obtained by forming pseudo tape from bundles of reinforcing filler, impregnated with polymer binder, passing through impregnation bath (annular reinforcement), winded with reinforcing filler without preliminary impregnation (axial reinforcement), of produced pseudo tape in circumferential direction on forming element with additional impregnation of axial reinforcement in lower point on surface of wound shell by means of rolling roller wetted by polymer binder, formation of a layer-by-layer winded wall of a shell from the obtained composite material by continuous movement of a pseudo tape stacker along the rotating shaping element with the set value of the pseudo tape stacker displacement per one revolution of the shaping element.

EFFECT: providing high specific bearing capacity per unit weight of shell; increased efficiency of winding of composite shell; improved dielectric properties of fiberglass.
