    摘要： The invention relates to fiber reinforcement for making an elongate mechanical part (10) out of composite material having a lug (14) at at least one end for receiving a pin for making a pivot connection with another part, the fiber reinforcement being made from a central fiber structure (106; 106′) for forming a core that is obtained by three-dimensional weaving, from a peripheral fiber structure (16; 16′) that is to form a belt surrounding the central structure so as to form at least one empty cylindrical space in the lug of the part, and from at least one annular fiber structure (112; 112′; 112″) that is to form a ring that is formed inside the empty space provided between the central structure and the peripheral structure.

    摘要： A jacquard type loom for making a fabric by weaving plural warp yarns with plural weft yarns, the fabric including a determined number of columns of warp yarns per unit length and a determined number of layers of weft yarns. The loom includes a comber board including plural holes passing a corresponding number of control cords, each control cord including an heddle eye through which a warp yarn passes. The holes are distributed in a determined number of columns extending parallel to the warp yarn direction and a determined number of rows per column extending in a direction perpendicular to the warp yarn direction. The comber board includes a number of columns of holes per unit length smaller than the number of warp columns in the same unit length in the fabric, and a number of rows of holes greater than the number of warp layers in the fabric.

    摘要： A fiber structure for reinforcing a composite material part, the structure being woven as a single piece by multilayer weaving between a first plurality of layers of yarns extending in a first direction and a second plurality of layers of yarns extending in a second direction. The second plurality of layers of yarns includes at least one layer of variable-weight yarns, each variable-weight yarn including a separable assembly of individual yarns, each having a determined weight. The fiber structure includes at least one portion of reduced thickness in which the variable-weight yarn presents a weight that is less than the weight that it presents prior to the reduced thickness portion.
