METHOD FOR PRODUCING A ONE-PIECE PREFORM FOR A COMPOSITE STRUCTURE

摘要

A method for producing a one-piece preform for a composite structure includes the following steps: positioning a plurality of bundles of warp threads over two pairs of harnesses; making movements of low amplitude of each of the pairs of harnesses so as to make at least two adjacent and separate layers; and making movements of higher amplitude of the pairs of harnesses so as to at least partially link the at least two adjacent layers to an least one portion of the preform.
