METHOD OF FORMING OF COMPOSITE MATERIAL OF EMPTY AERODYNAMIC SURFACES - 1 Russian patent published in 2018 - IPC B29C70/44 B29D22/00 

Abstract RU 2674972 C2

FIELD: moulding.

SUBSTANCE: invention relates to methods for forming articles from composite materials, such as fiberglass, carbon fiber, etc. Method consists in laying in the mold of sheets of reinforcing material impregnated with a binder, placing inside the sheets of elastic capacity and subsequent pumping of elastic capacity, and the number of elastic capacities is placed in the mold, the number of spars provided is larger by one. All tanks are inflated from a single source of air pressure through hoses, whose lengths are inversely proportional to the final volume of the containers, or whose cross-sectional areas are correlated in direct proportion to the volume of the cavities formed by the side members.

EFFECT: technical result of the invention is to increase the strength of the product.
