FIELD: weaving.
SUBSTANCE: fibrous structure (200) includes a plurality of weft layers (t1-t34) and a plurality of base layers (C1-C12) connected to each other by three-dimensional or multilayer weaving, wherein fibrous structure (200) includes at least first and second parts (203, 204), which adjoin each other in main direction, first part (203) has thickness in direction perpendicular to main and weft directions, which exceeds thickness second part (204). Weft layers (t13-t22) located in core (2031) of first part (203) of fibrous structure (200), include cords (10). Weft layers (t1-t12; t23-t34) passing on either side of weft layers (t13-t22), including cords (10), and up to shell (2032; 2033) of first part (203), include threads or bundles (20; 21; 22), wherein cords (10) have a cross-section which exceeds the cross-section of threads or bundles (20; 21; 22).
EFFECT: reinforcing fibrous structure is disclosed for parts from composite material with a wide range of thickness.
