Method of manufacturing a laminate (13) consisting of fibrous reinforcements (10) which are impregnated with thermosetting resin, characterised in that: a) the reinforcements (10) are placed in a mould (1); b) the mould is closed by a flexible membrane (6) forming the bottom of a cover (5) to which the membrane is bonded in a sealed manner; c) a vacuum is created between the mould (1) and the flexible membrane (6); d) the impregnation resin is injected into the mould between the latter and the flexible membrane; e) a fluid, under a pressure P of a few bar, is sent into the cover, that is to say into the chamber formed by the cover and the flexible membrane forming its bottom and closing the mould, while at the same time allowing the excess resin to escape via the resin-injection and vacuum-application channels. <IMAGE>
