摘要： The invention relates to a fibrous structure produced by multi-layer three-dimensional weaving with variable thickness, in a direction perpendicular to the warp (C) and weft (T) directions, in the warp direction while keeping the same number of woven warp threads at every point of the fibrous structure in the warp direction. During a transition to warp direction from a first portion of the fibrous texture to a second portion of the fibrous texture having a greater thickness than that of the first portion, the number of warp planes is reduced and the number of warp thread layers is increased without changing the number of warp threads, constituting at least one warp plane (Pl,...) in the second portion with warp threads from at least two different warp planes (Pl, P2,...) in the first portion.

摘要： The invention relates to a fibrous blank (100) woven in one piece by three-dimensional weaving for producing a platform with a closed box structure for a turbomachine fan made of composite material. In each plane of the fibrous blank, a set of warp threads connects together the layers of weft threads of the first (102), the second (104) and the third (106) part of the fibrous blank while forming a closed disconnect (108) separating the first part from the second part over a portion of the dimension of the fibrous blank in the warp direction between an upstream disconnect limit (108a) and a downstream disconnect limit (108b), and at least one open disconnect (110) separating the second part from the third part over a portion of the dimension of the fibrous blank in the warp direction from a disconnect limit (110a) to a downstream edge (100c) of the fibrous blank. The invention also relates to a method for manufacturing a preform of a platform having a closed box structure for a turbomachine fan made of composite material on the basis of such a fibrous blank.

摘要： The invention relates to a method (200) for the production of a fibrous metal structure (100) by means of weaving with metal weft yarns and metal warp yarns. The invention is characterised in that it includes a step comprising the weaving of the fibrous structure (100) by means of the successive weaving of metal clasps (301') that are used as weft yarns. For the purpose of weaving, each of the arms (302, 303) of each of the metal clasps (301') is introduced into at least one shed, each shed being formed by two warp yarns.
