FIELD: chemistry.SUBSTANCE: fibrous structure for making a composite part is made by three dimensional weaving and has a main portion and an edge adjacent to the main portion. The edge has a thickness (E4), which is greater than the thickness (E1) of the main portion. The edge has a first portion which is contiguous with the main portion and a second portion which is layered on the first portion. Said edge is adapted to bend towards the second portion such that said first and second portions respectively form a flange and a counter-flange for mounting said part.EFFECT: improved mechanical properties of the obtained articles.13 cl, 7 dwg |
