METHOD OF FABRICATING DIVER'S HELMET FROM LAMINAR COMPOSITE MATERIALS, MOULD FOR FABRICATION OF DIVER'S HELMET FROM LAMINAR COMPOSITE MATERIALS AND DIVER'S HELMET FROM LAMINAR COMPOSITE MATERIALS Russian patent published in 2012 - IPC B63C11/06 B32B7/08 A42B3/00 A42B3/06 

FIELD: process engineering.

SUBSTANCE: proposed method comprises using mould made up of glass-fibre-reinforced plastic half dies and base jointed together in plane of symmetry of helmet main surface, signs with shaping surface of basic planes and openings, and laying layers of shell from reinforcing fabric impregnated with polymer binder into said mould. Flanges of openings are filled with annular fibres to wrap said signs whereon pressure washers are fitted to press said washers toward basic surfaces. Said shell is moulded keeping mould cavity at pressure during curing of composite and covering neck opening by base and inflating rubber tube fitted there inside. Said mould is made up of glass-fibre-reinforced plastic half dies and base jointed together in plane of symmetry of helmet main surface, signs with shaping surface of basic planes and openings, porthole, assemblies of life-supporting system and communication as well as elements of labyrinth seals. Aforesaid openings are filled with annular fibres to wrap said signs whereon pressure washers are fitted to press said washers toward basic surfaces and covering neck opening by base and inflating rubber tube fitted there inside to create internal pressure. Diver's helmet comprises aforesaid elements.

EFFECT: higher tightness, reliability, decreased weight.
