PRODUCTION METHOD OF LARGE THREE-LAYER STRUCTURES FROM POLYMER COMPOSITES Russian patent published in 2009 - IPC B32B37/00 B32B23/00 

FIELD: engineering industry.

SUBSTANCE: invention refers to engineering industry and may be used for production of parts for space and earth dedication, namely sphere-conical-cylindrical panels of nose fairing of carrier boosters, adapter sections, instrument modules and platforms. On the full-size form there put is prepreg of inner base layer and reinforced area from carbon fiber-reinforced plastic in a form of soaked by binding agent of carbon filling compound, perforated glue film, aluminium honeycomb core with inserts, perforated glue film and prepreg of outer base layer from carbon fiber-reinforced plastic in a form of soaked by binding agent of carbon filling compound. Aluminium honeycomb core and inserts are fixed by glass bands duplicated with glue film strips. Obtained structure is bonded under vacuum pressure in furnace with simultaneous hardening of base layers prepregs and reinforced areas.

EFFECT: increase of structure production effectiveness, simplification of structure manufacturing, decrease of labour coefficient and assembly work volume, improvement of parts quality.
