Problems solved by technology

The same problem exists with the layers if they are not properly aligned under the needling head afterwards, resulting in a fabric structure that often exhibits edges that are not completely continuous and clean

Embodiment Construction

[0018] In a first embodiment of the invention, a circular needling table 10 is shown in a highly diagrammatic manner on figure 1 and 2 middle.

[0019] The invention applies to any circular needling process in which endless layers (or plies) of fabric are stacked on a platen and needled to form a needled fiber preform in the shape of an annular shape. The layers may be pre-formed as rings or ring sectors obtained by juxtaposing and cutting woven or non-woven materials composed of unidirectional or multidirectional fibers. They can also be formed as multiple turns wound flat by a feeding device such as that described in patent application WO 02 / 088449, or by multiple turns formed of deformable braids, or even by deformable two-dimensional fabrics (spiral fabrics or braid) formed in multiple turns.

[0020] The fibre-containing annular preform 12 for needling rests directly on a horizontal annular pressure plate 14 of the needling table. The fibrous annular preform 12 is dri...

Abstract

The invention provides a circular needling table (10) for needling a textile structure made from an annular fiber preform, wherein the table comprises: a horizontal annular platen (14) for having the annular fiber preform (12) placed thereon; drive means for driving the fiber preform in rotation about the axis (16) of the platen; a needling device (22) having a needling head (24) extending over an angular sector of the platen and driven in vertical motion relative to the platen; and guide means (38a, 38b) for guiding the fiber preform under the needling head.

Description

technical field [0001] The present invention relates to the general field of circular needling stations for the manufacture of needled textile structures from endless fiber preforms. Background technique [0002] It is known to use circular needling tables to produce endless fabric structures for forming fiber reinforcements for annular components made of composite material, in particular brake discs, for example for aircraft brakes Disks made of carbon / carbon (C / C) composites. [0003] The circular needling table generally includes a horizontal annular platen, a driving device (usually a friction drive device) and an acupuncture device. The annular fiber preform is placed on the horizontal annular platen. The driving device is used to drive the fiber preform around the platen. Rotating about an axis, the needling device has a needling head extending over an angled sector of the platen and driven to reciprocate vertically relative to the platen. Reference may be made to do...
