METHOD OF DEVICE FOR PRODUCTION OF CYLINDRICAL STRUCTURAL COMPONENTS Russian patent published in 2013 - IPC B29C70/44 B29D22/00 

Abstract RU 2488488 C2

FIELD: process engineering.

SUBSTANCE: set of invention relates to production of cylindrical structural component, particularly, fuselage cylindrical section. Proposed method comprises using cylindrical forming tool with inner forming surface corresponding to structural component outer shape. Then, fibrous cylindrical cloth is applied on expandable support bearing surface made so that, in unexpanded state, it enters the forming tool leaving enough space for expansion of bearing surface to forming surface. Note here that bearing surface is coated so that fibers extends in diagonal around the support. Then, said support is arranged in forming tool, fibrous cloth is pressed against forming surface by expanding the support and said cloth is impregnated with cured matrix. Proposed method comprises using cylindrical forming tool with inner forming surface corresponding to structural component outer shape. Device comprises also expandable support bearing surface made so that, in unexpanded state, it enters the forming tool leaving enough space for expansion of bearing surface to forming surface of 1 to 10 cm. Besides it comprises support expander to expand fibrous clot and press it against forming surface and means to impregnate said cloth with cured matrix.

EFFECT: higher quality of structural components.
