INSTALLATION ET PROCEDE DE MISE EN FORME D'UNE PREFORME FIBREUSE DE REVOLUTION PRESENTANT EN SECTION RADIALE UN PROFIL EVOLUTIF

摘要

An installation for shaping an axisymmetric fiber preform presenting a profile that varies in radial section, includes a storage mandrel for storing a fiber texture in the form of a wound strip, one or more follower rollers, and an axisymmetric mold, the storage mandrel, each follower roller, and the mold presenting across their axial widths radii that vary defining outside surfaces having respective profiles in relief, at least one follower roller including a plurality of roller segments, each extending over a fraction of the axial width of the follower roller, each roller segment including a platen defining a portion of the outside surface of the follower roller; and an actuator system suitable for moving the platen of the roller segment in a direction that is radial relative to the axis of the follower roller.
