PROCEDE DE FABRICATION D'UNE PIECE EN MATERIAU COMPOSITE AVEC AMELIORATION DE LA DENSIFICATION INTRA-FILS

摘要

A method of fabricating a composite material part comprises fiber reinforcement densified by a matrix. The method comprises the following steps: making a fiber fabric by weaving yarns having an initial mean fiber percentage; and densifying the fiber fabric with a matrix. The fiber fabric is subjected, prior to densification, to one or more jets of water under pressure so as to reduce the mean fiber percentage in the fabric to a value lying in the range 20% to 45%.
