SUPPORTING BEND FOR THIN-WALL SHELLS FROM COMPOSITE MATERIALS AND METHOD OF ITS MANUFACTURE Russian patent published in 2017 - IPC B64C1/10 B64F5/00 B29D99/00 B29C70/34 B29C70/40

Abstract RU 2623054 C1

FIELD: construction.

SUBSTANCE: reinforcing frame is a stiffener with contact surfaces in the form of a reinforced shell along the outer diameter and with an annular thickening along the inside. In this case, the stiffener is made by a flat or convex-concave double addition of the calculated number of layers of tissue with an inflection in the thickening zone and dilution of each half of the layers to the sides with the formation of developed contact surfaces. The circular thickening is formed by filling the calculated amount of a thread of a structural volume in the tissue inflection zone.

EFFECT: increase in mass-strength characteristics.
