PROCÉDÉ DE FABRICATION D'UNE PIÈCE COMPOSITE À BASE DE RÉSINE AQUEUSE ET PIÈCE COMPOSITE ISSUE D'UN TEL PROCÉDÉ
摘要:
The invention relates to a method for producing a composite part (10), said method comprising the following steps: - a step of stacking a first mat (12A), a spacer (14) and a second mat (12B) in a heatable mould (30); at least one of the mats comprising a continuous web (20) of fibres impregnated with a thermosetting resin (21); - a step involving compression and heating of the stack by the heatable mould, in order to polymerize the thermosetting resin. The stacking step comprises the deposition, in a heatable mould, of a first (22A) and a second (22B) filtration layer, in contact respectively with the first and second mats, on the opposite side from the spacer. The filtration layers are porous to steam and relatively less porous to the thermosetting resin. The heatable mould comprises means (36) for evacuation of steam (37) formed during the compression and heating step.
