Abstract
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.
