FIBROUS STRUCTURE WHICH HAS THREADS WITH VARIABLE YARN NUMBERS Russian patent published in 2017 - IPC D03D25/00 

FIELD: textiles, paper.

SUBSTANCE: invention relates to a fibrous structure (S1) for composite material parts reinforcement, wherein the noted structure is woven as a single integral piece by the multilayer weave between the first plurality of thread layers (t10, _{t20, t30}), extended in the first direction and the second plurality of thread layers (₁₀, 20, 30) extended in the second direction. A second plurality of thread layers comprises at least one thread layer (10) with variable weight, each thread with a variable weight is designed as a shareable set of individual threads (11, 12), each of which has a certain weight. The fibrous structure (S1) comprises at least one area (2G) with a reduced thickness, in which the thread (10) with a variable weight has a weight that is less than the weight which it had before the noted area with reduced thickness.

EFFECT: invention extends the fibrous structures product range for reinforcement materials.
