PROCESS FOR CONFORMING PREFORMS FOR THE MANUFACTURE OF PARTS OF THERMOSTRUCTURAL COMPOSITE MATERIAL, PARTICULARLY OF PARTS IN THE FORM OF SAILS OR PANELS.

摘要

P The conformation of the fibrous preform (10), in order to maintain it in a desired shape and with a desired degree of compaction, before densification by chemical vapor infiltration, is carried out by bonding the preform (10) on a conformator rigid (12) by means of wires (30) passing through the preform and passing through holes (14) in the former. The binding wires (30) are made of carbon or ceramic. Before binding, a covering layer (16) can be placed on the face of the preform (10) opposite to that facing the shaper. /P
