HOLLOW MULTI-LAYERED WOVEN FRAME WITH A THREE-DIMENSIONAL STRUCTURE AND METHOD FOR MANUFACTURE THEREOF Russian patent published in 2021 - IPC D03D11/00 

FIELD: textiles.

SUBSTANCE: invention relates to the textile industry, particularly to hollow multi-layered woven frames intended for creating reinforcing elements of composite materials, and to a method for manufacture thereof. The hollow multi-layered woven frame with a three-dimensional structure, formed on a circular weaving machine by interweaving weft threads and systems of warp threads has a structure wherein all warp threads by themselves or with chains of point thickenings or thinnings located thereon on the side of the outer surface and/or in depth are deflected from the generatrix of the frame in one direction or another at an angle of 10 degrees.

EFFECT: invention makes it possible to create such a structural implementation of a woven frame, which provides a possibility of setting the direction of rotation when used as a reinforcing element of composite materials in products in the form of bodies of rotation.
