Document Type and Number:
WIPO Patent Application WO/2013/088042
Kind Code:
A3
Abstract:
The invention relates to a fibrous preform (20), which is formed from a fiber structure woven by means of three-dimensional weaving, having a plurality of warp thread layers interconnected by woof threads from a plurality of woof thread layers. The fibrous preform has a first portion (12) and a second portion (14), which are located, as extensions of each other, in the woof direction and form an angle therebetween. In the folding area and in each woof plane of the fiber structure, two woof threads, located in an area adjacent to one outer surface of the fiber structure located inside the angle, have paths that intersect in such a manner that a slight curve is made in said threads.
