FIBER STRUCTURE HAVING VARIABLE-COUNT THREADS

摘要

The invention relates to a fiber structure (S1) for reinforcing a composite material part, said structure being woven into a single part by means of multilayer weaving between a first plurality of thread layers (t10, t20, t30), extending in a first direction and a second plurality of thread layers (10, 20, 30) extending in a second direction. The second plurality of thread layers includes at least one variable-count thread layer (10), each variable-count thread being formed from a separable set of unitary threads (11, 12) that each have a predetermined count. The fiber structure (S1) includes at least one portion (2G) having a reduced thickness, wherein the variable-count threads (10) have a count less than the one provided before said reduced-thickness portion.
