摘要： Three-dimensional fabric with oblique reinforcements comprising warp yarns (1), weft yarns (2) and oblique yarns (3a, 3b). The warp yarns (1) form at least two layers and run over different layer planes, with none of these yarns linking the two outermost fabric layers. The weft yarns (2) comprise at least two layers, disposed in superimposed planes, and are interlaced and woven with the warp yarns (1). The oblique yarns (3a, 3b) are disposed in layers of parallel yarns, forming one or more pairs, the directions of each layer of oblique yarns of one pair being symmetrical with one another in relation to the longitudinal fabric direction, and forming a non-right angle in relation to said longitudinal direction. The layers of oblique yarns (3a, 3b) are covered with at least one layer of non-oblique yarns. Application in the production of reinforcing elements for composite materials.
