METHOD FOR MANUFACTURING A PART MADE OF STRESS-RESISTANT COMPOSITE MATERIAL

摘要

A method for manufacturing a stress-resistant part made of a composite material, wherein the composite material is forced to flow in a channel belonging to a mold and delimited by a selectively heated wall, the fibers of the composite material assuming a statistically preferential orientation by means of the flow. The composite material comprises a thermosetting resin, the flow of this material in the channel and the heating of the wall of the channel are concomitant, and the temperature of the channel and the flow velocity of the composite material in the channel are determined with respect to each other so that the composite material flowing in this channel forms a fluid line, the mean cross-section of which decreases during the flow of this material in said channel due to the polymerization of the resin.
