FIBROUS STRUCTURE AND PART OF COMPOSITE MATERIAL CONTAINING SUCH A STRUCTURE Russian patent published in 2022 - IPC D03D25/00 

FIELD: composite materials.

SUBSTANCE: fibrous structure (200) contains a set of weft layers and warp layers interconnected by multilayer three-dimensional weave. Fibrous structure (200) contains at least first and second sections (203 and 204) adjacent in the warp direction, where first section (203) has, in a direction perpendicular to warp and weft directions, a thickness greater than a thickness of second section (204). In this case, first section (203) contains in its core (2031) at least one fibrous material (ML) obtained by means of three-dimensional weaving of warp threads and weft threads in the form of a mesh of false binding weave, and mentioned at least one material (ML) is located between two covering layers (2032, 2033) located near the surface of first section (203), and it is connected to covering layers (2032, 2033) by means of warp threads (C3, C16) that belong to the mentioned covering layers and that are locally tilted to the mentioned material.

EFFECT: obtaining a fibrous structure.
