Method of manufacturing a composite part, in particular a sandwich panel, from several assembled preforms.

摘要

PREFORMAS DIFFERENT ARE MADE TO DIFFERENT PARTS ONE PIECE composite material manufacture, and are assembled in a non-densified or not fully densified, BY LINK BETWEEN SURFACES RESPECTIVE CONTACT preforms (13, 15, 36) by fibrils (17, 19) MAKING OUTGOING perpendicular to the surface of a preform (13, 15) and in which the surface of another preform (36) MOVED. ASSEMBLED preforms are subsequently CODENSIFICADAS. Fibrils are formed on the surface of a molded Fibrous BY THIS fiber ends, displaced by Leaky PREFORMA. THE PROCESS IS SUITABLE IN PARTICULAR FOR PRODUCING A SANDWICH COMPOSITE PANEL COMPRISING RIGID BETWEEN TWO FUR IS WILLING SOUL WHICH FORMED BY SKINS perpendicular to SEPTA.
