Abstract

The invention relates to fiber reinforcement for making an elongate mechanical part () out of composite material having a lug () 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 (') for forming a core that is obtained by three-dimensional weaving, from a peripheral fiber structure (′) 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 (″) that is to form a ring that is formed inside the empty space provided between the central structure and the peripheral structure.
