    摘要: The invention relates to a process for manufacturing a composite connecting rod (6) from three-dimensional fabric of reinforcing fibres, this connecting rod (6) extending along one main direction, comprising the operations of: - cutting one or more base parts (7, 8) from a three-dimensional fabric; cutting one or more reinforcing parts (9, 10) from a three-dimensional fabric; - installing the various parts (7, 8, 9, 10) on a support in order to shape them; - firmly attaching the various parts (7, 8, 9, 10) to one another by stitching (12, 13, 14, 15) with reinforcing fibres in order to form a preform of reinforcing fibres; - installing the preform on a mandrel; - injecting resin into the preform and polymerization of this resin.

    摘要: The invention relates to a method for braiding reinforcing fibres on a mandrel (8) using a machine comprising a ring (9) carrying at least two series of spools of fibres, by moving this mandrel at a predetermined feed rate and by moving the two series of spools along the ring (9) so that they crisscross by rotating in opposite directions at a predetermined speed of rotation about an axis (AX) of this ring, the braid being formed on the mandrel (8) at a region of convergence (R) of the fibres which together delimit a conical shape (C), characterized in that it comprises: a step of reconfiguring the machine in which the angle (a2) at the vertex of the cone (C) delimited by the fibres adopts a new value (a2); a step of resuming braiding in which the movement of the spools along the ring (9) and the feed rate of the mandrel (8) are re-established at a new feed rate and a new rotational speed.
