Abstract
A fibrous texture intended to form the fibrous reinforcement of a turbomachine part, includes first yarns bonded with second yarns, and at least one vibration damping element of viscoelastic material present in a recess defined by a second de-bonding zone, the de-bonding zone separating, on a portion of the texture, a first surface part of the texture from a second part of the texture formed by a three-dimensional fabric in which the first yarns are bonded with the second yarns, the first surface part of the texture being formed by a unidimensional layer of first yarns or being formed by a two-dimensional fabric in which the first yarns are bonded with the second yarns.

A woven fibrous texture intended to form a fibrous reinforcement of a turbomachine part, comprising first yarns bonded with second yarns, and at least one vibration damping element of viscoelastic material present in a recess defined by a de-bonding zone, said de-bonding zone separating, on a portion of the woven fibrous texture, a first surface part of the woven fibrous texture from a second part of the woven fibrous texture formed by a three-dimensional fabric in which the first yarns are bonded with the second yarns, the first surface part of the woven fibrous texture being formed by a unidimensional layer of first yarns only comprising first yarns extending essentially in a same direction, or by a two-dimensional fabric in which the first yarns are bonded with the second yarns.
