Brief description of the braiding of fibers reinforcements a variation of inclination of the fibers plaited

摘要

The invention relates to a method of braiding reinforcing fibers on a mandrel (8) with a machine having a ring (9) carrying at least two series of reels of fibers, by moving the mandrel at a predetermined forward speed while moving the two series of reels along the ring (9) so that they cross while rotating in opposite directions and at a predetermined speed of rotation about an axis (AX) of the ring, the braid being formed on the mandrel (8) in the vicinity of a region of convergence (R) of the fibers that together define a conical shape (C), the method being characterized in that it comprises: a step of reconfiguring the machine in which the angle (a2) at the apex of the cone (C) defined by the fibers takes on a new value (a2); and a step of restarting braiding in which the movement of the reels along the ring (9) and the forward movement of the mandrel (8) are re-established with a new speed of rotation and a new speed of advance.
