发明名称 FIBER STRUCTURE WOVEN INTO A SINGLE PART BY MEANS OF 3D WEAVING, AND USE IN THE MANUFACTURE OF A COMPOSITE MATERIAL PART
摘要 In a fiber structure woven into a single part by means of three-dimensional weaving, first woof threads connect therebetween warp thread layers from a first portion (1) of the fiber structure (10), which are adjacent to a disconnection (16), with warp thread layers from a second portion (14) of the fiber structure, which are located beyond the disconnection, and second woof threads connect therebetween warp thread layers from the second portion (14) of the fiber structure, which are adjacent to the disconnection, with warp thread layers from the first portion (12) of the fiber structure, which are located beyond the disconnection, such that the paths of the first and second woof threads intersect in at least one transition area (18) extending into the fiber structure from the base of the disconnection, the transition area extending over a distance greater than the pitch (p) between adjacent warp columns in the woof direction.
