Abstract
A woven fiber structure presenting over at least one of its outside faces a satin weave formed by interlinking a first set of yarns with a second set of yarns; wherein the first set of yarns is in the majority over the outside face, the first set of yarns being formed by a mixture of yarns having an S-twist and of yarns having a Z-twist.

A woven fiber structure comprising yarns made of a carbon precursor and presenting over at least one of its outside faces a satin weave formed by interlinking a first set of yarns with a second set of yarns;
- wherein the first set of yarns is in the majority over the outside face, said first set of yarns being formed by a mixture of yarns having an S-twist and of yarns having a Z-twist;
- and wherein the structure includes over its outside face:
- a first yarn of the second set of yarns forming a first set of satin points;
- a second yarn of the second set of yarns, adjacent to the first yarn of the second set of yarns, and forming a second set of satin points, the satin points of the second set being offset from the satin points of the first set by a first spacing;
- and
- a third yarn of the second set of yarns, adjacent to the second yarn of the second set of yarns, and forming a third set of satin points, the satin points of the third set being offset from the satin points of the second set by a second spacing different from the first spacing.
